-#      double-quoted (when needed), suitable for a subsequent eval
-#  ii) func_quote_arg_unquoted_result
-#      has all characters that are still active within double
-#      quotes backslashified.  Available only if 'unquoted' is specified.
-#
-# Available modes:
-# ----------------
-# 'eval' (default)
-#       - escape shell special characters
-# 'expand'
-#       - the same as 'eval';  but do not quote variable references
-# 'pretty'
-#       - request aesthetic output, i.e. '"a b"' instead of 'a\ b'.  This might
-#         later used in func_quote to get output like: 'echo "a b"' instead of
-#         'echo a\ b'.  This is slower than default on some shells.
-# 'unquoted'
-#       - produce also $func_quote_arg_unquoted_result which does not contain
-#         wrapping double-quotes.
-#
-# Examples for 'func_quote_arg pretty,unquoted string':
-#
-#   string      | *_result              | *_unquoted_result
-#   ------------+-----------------------+-------------------

+On Linux, install the development packages for FreeType,
+Cairo, and GLib. For example, on Ubuntu / Debian, you would do:
+
+    sudo apt-get install gcc g++ libfreetype6-dev libglib2.0-dev libcairo2-dev
+
+whereas on Fedora, RHEL, CentOS, and other Red Hat based systems you would do:
+
+    sudo yum install gcc gcc-c++ freetype-devel glib2-devel cairo-devel
+
+on Windows, consider using [vcpkg](https://github.com/Microsoft/vcpkg),
+provided by Microsoft, for building HarfBuzz and other open-source libraries
+but if you need to build harfbuzz from source, put ragel binary on your
+PATH and follow appveyor CI's cmake
+[build steps](https://github.com/harfbuzz/harfbuzz/blob/master/appveyor.yml).
+
+on macOS, using MacPorts:
+
+    sudo port install freetype glib2 cairo
+
+or using Homebrew:
+
+    brew install freetype glib cairo
+
+If you are using a tarball, you can now proceed to running configure and make
+as with any other standard package. That should leave you with a shared
+library in `src/`, and a few utility programs including `hb-view` and `hb-shape`
+under `util/`.
+
+If you are bootstrapping from git, you need a few more tools before you can
+run `autogen.sh` for the first time. Namely, `pkg-config` and `ragel`.
+
+Again, on Ubuntu / Debian:
+
+    sudo apt-get install autoconf automake libtool pkg-config ragel gtk-doc-tools
+
+and on Fedora, RHEL, CentOS:
+
+    sudo yum install autoconf automake libtool pkgconfig ragel gtk-doc
+
+on the Mac, using MacPorts:
+
+    sudo port install autoconf automake libtool pkgconfig ragel gtk-doc
+
+or using Homebrew:
+
+    brew install autoconf automake libtool pkgconfig ragel gtk-doc
+
+To build the Python bindings, you also need:
+
+    brew install pygobject3

+# Configuring HarfBuzz
+
+Most of the time you will not need any custom configuration.  The configuration
+options provided by `configure` or `cmake` should be enough.  In particular,
+if you just want HarfBuzz library plus hb-shape / hb-view utilities, make sure
+FreeType and Cairo are available and found during configuration.
+
+If you are building for distribution, you should more carefully consider whether
+you need Glib, ICU, Graphite2, as well as CoreText / Uniscribe / DWrite.  Make
+sure the relevant ones are enabled.
+
+If you are building for custom environment (embedded, downloadable app, etc)
+where you mostly just want to call `hb_shape()` and the binary size of the
+resulting library is very important to you, the rest of this file guides you
+through your options to disable features you may not need, in exchange for
+binary size savings.
+
+## Compiler Options
+
+Make sure you build with your compiler's "optimize for size" option.  On `gcc`
+this is `-Os`, and can be enabled by passing `CXXFLAGS=-Os` either to `configure`
+(sticky) or to `make` (non-sticky).  On clang there is an even more extreme flag,
+`-Oz`.
+
+HarfBuzz heavily uses inline functions and the optimize-size flag can make the
+library smaller by 20% or more.  Moreover, sometimes, based on the target CPU,
+the optimize-size builds perform *faster* as well, thanks to lower code
+footprint and caching effects.  So, definitely try that even if size is not
+extremely tight but you have a huge application.  For example, Chrome does
+that.  Note that this configuration also automatically enables certain internal
+optimizations.  Search for `HB_OPTIMIZE_SIZE` for details, if you are using
+other compilers, or continue reading.
+
+Another compiler option to consider is "link-time optimization", also known as
+'lto'.  To enable that, with `gcc` or `clang`, add `-flto` to both `CXXFLAGS`
+and `LDFLAGS`, either on `configure` invocation (sticky) or on `make` (non-sticky).
+This, also, can have a huge impact on the final size, 20% or more.
+
+Finally, if you are making a static library build or otherwise linking the
+library into your app, make sure your linker removes unused functions.  This
+can be tricky and differ from environment to environment, but you definitely
+want to make sure this happens.  Otherwise, every unused public function will
+be adding unneeded bytes to your binary.  The following pointers might come
+handy:
+
+ * https://lwn.net/Articles/741494/ (all of the four-part series)
+ * https://elinux.org/images/2/2d/ELC2010-gc-sections_Denys_Vlasenko.pdf
+
+Combining the above three build options should already shrink your library a lot.
+The rest of this file shows you ways to shrink the library even further at the
+expense of removing functionality (that may not be needed).  The remaining
+options are all enabled by defining pre-processor macros, which can be done
+via `CXXFLAGS` or `CPPFLAGS` similarly.
+
+
+## Unicode-functions
+
+Access to Unicode data can be configured at compile time as well as run-time.
+By default, HarfBuzz ships with its own compact subset of properties from
+Unicode Character Database that it needs.  This is a highly-optimized
+implementation that depending on compile settings (optimize-size or not)
+takes around ~40kb or ~60kb.  Using this implementation (default) is highly
+recommended, as HarfBuzz always ships with data from latest version of Unicode.
+This implementation can be disabled by defining `HB_NO_UCD`.
+
+For example, if you are enabling ICU as a built-in option, or GLib, those
+can provide Unicode data as well, so defining `HB_NO_UCD` might save you
+space without reducing functionality (to the extent that the Unicode version
+of those implementations is recent.)
+
+If, however, you provide your own Unicode data to HarfBuzz at run-time by
+calling `hb_buffer_set_unicode_funcs` on every buffer you create, and you do
+not rely on `hb_unicode_funcs_get_default()` results, you can disable the
+internal implementation by defining both `HB_NO_UCD` and `HB_NO_UNICODE_FUNCS`.
+The latter is needed to guard against accidentally building a library without
+any default Unicode implementations.
+
+
+## Font-functions
+
+Access to certain font functionalities can also be configured at run-time.  By
+default, HarfBuzz uses an efficient internal implementation of OpenType
+functionality for this.  This internal implementation is called `hb-ot-font`.
+All newly-created `hb_font_t` objects by default use `hb-ot-font`.  Using this
+is highly recommended, and is what fonts use by default when they are created.
+
+Most embedded uses will probably use HarfBuzz with FreeType using `hb-ft.h`.
+In that case, or if you otherwise provide those functions by calling
+`hb_font_set_funcs()` on every font you create, you can disable `hb-ot-font`
+without loss of functionality by defining `HB_NO_OT_FONT`.
+
+
+## Shapers
+
+Most HarfBuzz clients use it for the main shaper, called "ot".  However, it
+is legitimate to want to compile HarfBuzz with only another backend, eg.
+CoreText, for example for an iOS app.  For that, you want `HB_NO_OT_SHAPE`.
+If you are going down that route, check if you want `HB_NO_OT`.
+
+This is very rarely what you need.  Make sure you understand exactly what you
+are doing.
+
+Defining `HB_NO_FALLBACK_SHAPE` however is pretty harmless.  That removes the
+(unused) "fallback" shaper.
+
+
+## Thread-safety
+
+By default HarfBuzz builds as a thread-safe library.  The exception is that
+the `HB_TINY` predefined configuring (more below) disables thread-safety.
+
+If you do /not/ need thread-safety in the library (eg. you always call into
+HarfBuzz from the same thread), you can disable thread-safety by defining
+`HB_NO_MT`.  As noted already, this is enabled by `HB_TINY`.
+
+
+## Pre-defined configurations
+
+The [`hb-config.hh`](src/hb-config.hh) internal header supports three
+pre-defined configurations as well grouping of various configuration options.
+The pre-defined configurations are:
+
+  * `HB_MINI`: Disables shaping of AAT as well as legacy fonts.  Ie. it produces
+    a capable OpenType shaper only.
+
+  * `HB_LEAN`: Disables various non-shaping functionality in the library, as well
+    as esoteric or rarely-used shaping features.  See the definition for details.
+
+  * `HB_TINY`: Enables both `HB_MINI` and `HB_LEAN` configurations, as well as
+    disabling thread-safety and debugging, and use even more size-optimized data
+    tables.
+
+
+## Tailoring configuration
+
+Most of the time, one of the pre-defined configuration is exactly what one needs.
+Sometimes, however, the pre-defined configuration cuts out features that might
+be desired in the library.  Unfortunately there is no quick way to undo those
+configurations from the command-line.  But one can add a header file called
+`config-override.h` to undefine certain `HB_NO_*` symbols as desired.  Then
+define `HAVE_CONFIG_OVERRIDE_H` to make `hb-config.hh` include your configuration
+overrides at the end.
+
+
+## Notes
+
+Note that the config option `HB_NO_CFF`, which is enabled by `HB_LEAN` and
+`HB_TINY` does /not/ mean that the resulting library won't work with CFF fonts.
+The library can shape valid CFF fonts just fine, with or without this option.
+This option disables (among other things) the code to calculate glyph exntents
+for CFF fonts.

+For the development of HarfBuzz, the Microsoft shaping technology, Uniscribe,
+as a widely used and tested shaper is used as more-or-less OpenType reference
+implementation and that specially is important where OpenType specification
+is or wasn't that clear. For having access to Uniscribe on Linux/macOS these
+steps are recommended:
+
+1. Install Wine from your favorite package manager.  On Fedora that's `dnf install wine`.
+
+2. And `mingw-w64` compiler.
+   With `brew` on macOS, you can have it like `brew install mingw-w64`.
+   On Fedora, with `dnf install mingw32-gcc-c++`, or `dnf install mingw64-gcc-c++` for the
+   64-bit Windows.
+
+3. Install cross-compiled dependency packages.  Alternatively see [^1] below.
+   On Fedora that would be `dnf install mingw32-glib2 mingw32-cairo mingw32-freetype`
+   for 32-bit, or `dnf install mingw64-glib2 mingw64-cairo mingw64-freetype` for 64-bit.
+
+5. `NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild`
+
+6. Run `../mingw32.sh` for 32-bit build, or `../mingw64.sh` for 64-bit.  This configures
+   HarfBuzz for cross-compiling.  It enables Uniscribe backend as well.
+
+7. `make`
+
+Now you can use hb-shape using `wine util/hb-shape.exe` but if you like to shape with
+the Microsoft Uniscribe,
+
+8. Bring a 32bit version of `usp10.dll` for yourself from `C:\Windows\SysWOW64\usp10.dll` of your
+   Windows installation (assuming you have a 64-bit installation, otherwise
+   `C:\Windows\System32\usp10.dll`) that it is not a DirectWrite proxy
+   ([for more info](https://en.wikipedia.org/wiki/Uniscribe)).
+   Rule of thumb, your `usp10.dll` should have a size more than 500kb, otherwise
+   it is designed to work with DirectWrite which Wine can't work with its original one.
+   You want a Uniscribe from Windows 7 or older.
+
+   Put the DLL in the folder you are going to run the next command,
+
+9. `WINEDLLOVERRIDES="usp10=n" wine util/hb-shape.exe fontname.ttf -u 0061,0062,0063 --shaper=uniscribe`
+
+(`0061,0062,0063` means `abc`, use test/shaping/hb-unicode-decode to generate ones you need)
+
+
+[^1] Download and put [this](https://drive.google.com/open?id=0B3_fQkxDZZXXbWltRGd5bjVrUDQ)
+     in your `~/.local/i686-w64-mingw32`.  Then replace all the instances of
+     `/home/behdad/.local/i586-mingw32msvc` and `/home/behdad/.local/i686-w64-mingw32`
+     with `<$HOME>/.local/i686-w64-mingw32` on that folder.
+     (`<$HOME>` replace it with `/home/XXX` or `/Users/XXX` on macOS)
+     You shouldn't replace the instances of those inside binary files.

+To enable HarfBuzz bindings for Python among other languages, make sure
+you have latest version of gobject-introspection available.  On Ubuntu,
+you can install that this way:
+
+```bash
+sudo apt-get install libgirepository1.0-dev
+```
+
+And then run `autogen.sh` (if building from git), and then:
+
+```bash
+./configure --with-gobject --enable-introspection
+```
+
+Make sure that gobject-introspection is reported enabled then in the `configure` script output.
+
+Compile and install.
+
+Make sure you have the installation lib dir in `LD_LIBRARY_PATH`, as needed
+for the linker to find the library.
+
+Then make sure you also have `GI_TYPELIB_PATH` pointing to the resulting
+`$prefix/lib/girepository-*` directory.
+
+Make sure you have pygobject installed.  Then check that the following
+import works in your Python interpreter:
+
+```python
+from gi.repository import HarfBuzz
+```
+
+If it does, you are ready to call HarfBuzz from Python!  Congratulations.
+See [`src/sample.py`](src/sample.py).
+
+The Python API will change.  Let us know on the mailing list if you are
+using it, and send lots of feedback.

+HarfBuzz release walk-through checklist:
+
+1. Open gitk and review changes since last release.
+
+   * `git diff $(git describe | sed 's/-.*//').. src/*.h` prints all public API
+     changes.
+
+     Document them in NEWS.  All API and API semantic changes should be clearly
+     marked as API additions, API changes, or API deletions.  Document
+     deprecations.  Ensure all new API / deprecations are in listed correctly in
+     docs/harfbuzz-sections.txt.  If release added new API, add entry for new
+     API index at the end of docs/harfbuzz-docs.xml.
+
+     If there's a backward-incompatible API change (including deletions for API
+     used anywhere), that's a release blocker.  Do NOT release.
+
+2. Based on severity of changes, decide whether it's a minor or micro release
+   number bump,
+
+3. Search for REPLACEME on the repository and replace it with the chosen version
+   for the release.
+
+4. Make sure you have correct date and new version at the top of NEWS file,
+
+5. Bump version in configure.ac line 3,
+
+6. Do "make distcheck", if it passes, you get a tarball.
+   Otherwise, fix things and commit them separately before making release,
+   Note: Check src/hb-version.h and make sure the new version number is
+   there.  Sometimes, it does not get updated.  If that's the case,
+   "touch configure.ac" and rebuild.  Also check that there is no hb-version.h
+   in your build/src file. Typically it will fail the distcheck if there is.
+   That's what happened to 2.0.0 going out with 1.8.0 hb-version.h...  So, that's
+   a clue.
+
+7. Now that you have release files, commit NEWS, configure.ac, and src/hb-version.h,
+   as well as any REPLACEME changes you made.  The commit message is simply the
+   release number.  Eg. "1.4.7"
+
+8. "make dist" again to get a tarball with your new commit in the ChangeLog.  Then
+   "make release-files".  Enter your GPG password.  This creates a sha256 hash
+   and signs it.  Check the size of the three resulting files.
+
+9. Tag the release and sign it: Eg. "git tag -s 1.4.7 -m 1.4.7".  Enter your
+   GPG password again.
+
+10. Build win32 bundle.
+
+   a. Build Win32 binaries.  See [README.mingw.md](README.mingw.md).
+
+   b. Run "make dist-win" to build Win32 bundle.
+
+11. Copy all artefacts to users.freedesktop.org and move them into
+    `/srv/www.freedesktop.org/www/software/harfbuzz/release` There should be four
+    files.  Eg.:
+ ```
+-rw-r--r--  1 behdad eng 1592693 Jul 18 11:25 harfbuzz-1.4.7.tar.xz
+-rw-r--r--  1 behdad eng      89 Jul 18 11:34 harfbuzz-1.4.7.tar.xz.sha256
+-rw-r--r--  1 behdad eng     339 Jul 18 11:34 harfbuzz-1.4.7.tar.xz.sha256.asc
+-rw-r--r--  1 behdad eng 2895619 Jul 18 11:34 harfbuzz-1.4.7-win32.zip
+```
+
+12. While doing that, quickly double-check the size of the .tar.xz and .zip
+    files against their previous releases to make sure nothing bad happened.
+    They should be in the ballpark, perhaps slightly larger.  Sometimes they
+    do shrink, that's not by itself a stopper.
+
+13. Push the commit and tag out: "git push --follow-tags".  Make sure it's
+    pushed both to freedesktop repo and github.
+
+14. Go to GitHub release page [here](https://github.com/harfbuzz/harfbuzz/releases),
+    edit the tag, upload artefacts and NEWS entry and save.

+    <note>
+      <para>
+        The current HarfBuzz codebase is versioned 2.x.x and is stable
+	and under active maintenance. This is what is used in latest
+	versions of Firefox, GNOME, ChromeOS, Chrome, LibreOffice,
+	XeTeX, Android, and KDE, among other places. 
+      </para>
+      <para>
+        Prior to 2012, the original HarfBuzz codebase (which, these
+	days, is referred to as <emphasis>harfbuzz-old</emphasis>) was 
+        derived from code in <ulink
+	url="http://freetype.org/">FreeType</ulink>, <ulink
+	url="http://pango.org/">Pango</ulink>, and 
+        <ulink url="http://qt-project.org/">Qt</ulink>.
+        It is <emphasis>not</emphasis> actively developed or
+	maintained, and is extremely buggy. All users of harfbuzz-old
+	are encouraged to switch over to the new HarfBuzz as soon as possible.
+      </para>
+      <para>
+	To make this distinction clearer in discussions, the current
+	HarfBuzz codebase is sometimes referred to as
+	<emphasis>harfbuzz-ng</emphasis>.
+      </para>
+      <para>
+	For reference purposes, the harfbuzz-old source tree is archived 
+        <ulink
+	    url="http://cgit.freedesktop.org/harfbuzz.old/">here</ulink>. There
+	are no release tarballs of harfbuzz-old whatsoever.

+  <title>Buffers, language, script and direction</title>
+  <para>
+    The input to the HarfBuzz shaper is a series of Unicode characters, stored in a
+    buffer. In this chapter, we'll look at how to set up a buffer with
+    the text that we want and how to customize the properties of the
+    buffer. We'll also look at a piece of lower-level machinery that
+    you will need to understand before proceeding: the functions that
+    HarfBuzz uses to retrieve Unicode information.
+  </para>
+  <para>
+    After shaping is complete, HarfBuzz puts its output back
+    into the buffer. But getting that output requires setting up a
+    face and a font first, so we will look at that in the next chapter
+    instead of here.
+  </para>
+  <section id="creating-and-destroying-buffers">
+    <title>Creating and destroying buffers</title>
+    <para>
+      As we saw in our <emphasis>Getting Started</emphasis> example, a
+      buffer is created and 
+      initialized with <function>hb_buffer_create()</function>. This
+      produces a new, empty buffer object, instantiated with some
+      default values and ready to accept your Unicode strings.
+    </para>
+    <para>
+      HarfBuzz manages the memory of objects (such as buffers) that it
+      creates, so you don't have to. When you have finished working on 
+      a buffer, you can call <function>hb_buffer_destroy()</function>:
+    </para>
+    <programlisting language="C">
+      hb_buffer_t *buf = hb_buffer_create();
+      ...
+      hb_buffer_destroy(buf);
+    </programlisting>
+    <para>
+      This will destroy the object and free its associated memory -
+      unless some other part of the program holds a reference to this
+      buffer. If you acquire a HarfBuzz buffer from another subsystem
+      and want to ensure that it is not garbage collected by someone
+      else destroying it, you should increase its reference count:
+    </para>
+    <programlisting language="C">
+      void somefunc(hb_buffer_t *buf) {
+      buf = hb_buffer_reference(buf);
+      ...
+    </programlisting>
+    <para>
+      And then decrease it once you're done with it:
+    </para>
+    <programlisting language="C">
+      hb_buffer_destroy(buf);
+      }
+    </programlisting>
+    <para>
+      While we are on the subject of reference-counting buffers, it is
+      worth noting that an individual buffer can only meaningfully be
+      used by one thread at a time.
+    </para>
+    <para>
+      To throw away all the data in your buffer and start from scratch,
+      call <function>hb_buffer_reset(buf)</function>. If you want to
+      throw away the string in the buffer but keep the options, you can
+      instead call <function>hb_buffer_clear_contents(buf)</function>.
+    </para>
+  </section>
+  
+  <section id="adding-text-to-the-buffer">
+    <title>Adding text to the buffer</title>
+    <para>
+      Now we have a brand new HarfBuzz buffer. Let's start filling it
+      with text! From HarfBuzz's perspective, a buffer is just a stream
+      of Unicode code points, but your input string is probably in one of
+      the standard Unicode character encodings (UTF-8, UTF-16, or
+      UTF-32). HarfBuzz provides convenience functions that accept
+      each of these encodings:
+      <function>hb_buffer_add_utf8()</function>,
+      <function>hb_buffer_add_utf16()</function>, and
+      <function>hb_buffer_add_utf32()</function>. Other than the
+      character encoding they accept, they function identically.
+    </para>
+    <para>
+      You can add UTF-8 text to a buffer by passing in the text array,
+      the array's length, an offset into the array for the first
+      character to add, and the length of the segment to add:
+    </para>
+    <programlisting language="C">
+    hb_buffer_add_utf8 (hb_buffer_t *buf,
+                    const char *text,
+                    int text_length,
+                    unsigned int item_offset,
+                    int item_length)
+    </programlisting>
+    <para>
+      So, in practice, you can say:
+    </para>
+    <programlisting language="C">
+      hb_buffer_add_utf8(buf, text, strlen(text), 0, strlen(text));
+    </programlisting>
+    <para>
+      This will append your new characters to
+      <parameter>buf</parameter>, not replace its existing
+      contents. Also, note that you can use <literal>-1</literal> in
+      place of the first instance of <function>strlen(text)</function>
+      if your text array is NULL-terminated. Similarly, you can also use
+      <literal>-1</literal> as the final argument want to add its full
+      contents.
+    </para>
+    <para>
+      Whatever start <parameter>item_offset</parameter> and
+      <parameter>item_length</parameter> you provide, HarfBuzz will also
+      attempt to grab the five characters <emphasis>before</emphasis>
+      the offset point and the five characters
+      <emphasis>after</emphasis> the designated end. These are the
+      before and after "context" segments, which are used internally
+      for HarfBuzz to make shaping decisions. They will not be part of
+      the final output, but they ensure that HarfBuzz's
+      script-specific shaping operations are correct. If there are
+      fewer than five characters available for the before or after
+      contexts, HarfBuzz will just grab what is there.
+    </para>
+    <para>
+      For longer text runs, such as full paragraphs, it might be
+      tempting to only add smaller sub-segments to a buffer and
+      shape them in piecemeal fashion. Generally, this is not a good
+      idea, however, because a lot of shaping decisions are
+      dependent on this context information. For example, in Arabic
+      and other connected scripts, HarfBuzz needs to know the code
+      points before and after each character in order to correctly
+      determine which glyph to return.
+    </para>
+    <para>
+      The safest approach is to add all of the text available, then
+      use <parameter>item_offset</parameter> and
+      <parameter>item_length</parameter> to indicate which characters you
+      want shaped, so that HarfBuzz has access to any context.
+    </para>
+    <para>
+      You can also add Unicode code points directly with
+      <function>hb_buffer_add_codepoints()</function>. The arguments
+      to this function are the same as those for the UTF
+      encodings. But it is particularly important to note that
+      HarfBuzz does not do validity checking on the text that is added
+      to a buffer. Invalid code points will be replaced, but it is up

+    <para>
+      Buffers containing input characters still need several
+      properties set before HarfBuzz can shape their text correctly.
+    </para>
+    <para>
+      Initially, all buffers are set to the
+      <literal>HB_BUFFER_CONTENT_TYPE_INVALID</literal> content
+      type. After adding text, the buffer should be set to
+      <literal>HB_BUFFER_CONTENT_TYPE_UNICODE</literal> instead, which
+      indicates that it contains un-shaped input
+      characters. After shaping, the buffer will have the
+      <literal>HB_BUFFER_CONTENT_TYPE_GLYPHS</literal> content type.
+    </para>
+    <para>
+      <function>hb_buffer_add_utf8()</function> and the
+      other UTF functions set the content type of their buffer
+      automatically. But if you are reusing a buffer you may want to
+      check its state with
+      <function>hb_buffer_get_content_type(buffer)</function>. If
+      necessary you can set the content type with
+    </para>
+    <programlisting language="C">
+      hb_buffer_set_content_type(buf, HB_BUFFER_CONTENT_TYPE_UNICODE);
+    </programlisting>
+    <para>
+      to prepare for shaping.
+    </para>
+    <para>
+      Buffers also need to carry information about the script,
+      language, and text direction of their contents. You can set
+      these properties individually:
+    </para>
+    <programlisting language="C">
+      hb_buffer_set_direction(buf, HB_DIRECTION_LTR);
+      hb_buffer_set_script(buf, HB_SCRIPT_LATIN);
+      hb_buffer_set_language(buf, hb_language_from_string("en", -1));
+    </programlisting>
+    <para>
+      However, since these properties are often the repeated for
+      multiple text runs, you can also save them in a
+      <literal>hb_segment_properties_t</literal> for reuse:
+    </para>
+    <programlisting language="C">
+      hb_segment_properties_t *savedprops;
+      hb_buffer_get_segment_properties (buf, savedprops);
+      ...
+      hb_buffer_set_segment_properties (buf2, savedprops);
+    </programlisting>
+    <para>
+      HarfBuzz also provides getter functions to retrieve a buffer's
+      direction, script, and language properties individually.
+    </para>
+    <para>
+      HarfBuzz recognizes four text directions in
+      <type>hb_direction_t</type>: left-to-right
+      (<literal>HB_DIRECTION_LTR</literal>), right-to-left (<literal>HB_DIRECTION_RTL</literal>),
+      top-to-bottom (<literal>HB_DIRECTION_TTB</literal>), and
+      bottom-to-top (<literal>HB_DIRECTION_BTT</literal>).  For the
+      script property, HarfBuzz uses identifiers based on the
+      <ulink
+      url="https://unicode.org/iso15924/">ISO 15924
+      standard</ulink>. For languages, HarfBuzz uses tags based on the

+    </para>
+    <para>
+      Two additional buffer properties to be aware of are the
+      "invisible glyph" and the replacement code point. The
+      replacement code point is inserted into buffer output in place of
+      any invalid code points encountered in the input. By default, it
+      is the Unicode <literal>REPLACEMENT CHARACTER</literal> code
+      point, <literal>U+FFFD</literal> "&#xFFFD;". You can change this with
+    </para>
+    <programlisting language="C">
+      hb_buffer_set_replacement_codepoint(buf, replacement);
+    </programlisting>
+    <para>
+      passing in the replacement Unicode code point as the
+      <parameter>replacement</parameter> parameter.
+    </para>
+    <para>
+      The invisible glyph is used to replace all output glyphs that
+      are invisible. By default, the standard space character
+      <literal>U+0020</literal> is used; you can replace this (for
+      example, when using a font that provides script-specific
+      spaces) with 
+    </para>
+    <programlisting language="C">
+      hb_buffer_set_invisible_glyph(buf, replacement_glyph);
+    </programlisting>
+    <para>
+      Do note that in the <parameter>replacement_glyph</parameter>
+      parameter, you must provide the glyph ID of the replacement you
+      wish to use, not the Unicode code point.
+    </para>
+    <para>
+      HarfBuzz supports a few additional flags you might want to set
+      on your buffer under certain circumstances. The
+      <literal>HB_BUFFER_FLAG_BOT</literal> and
+      <literal>HB_BUFFER_FLAG_EOT</literal> flags tell HarfBuzz
+      that the buffer represents the beginning or end (respectively)
+      of a text element (such as a paragraph or other block). Knowing
+      this allows HarfBuzz to apply certain contextual font features
+      when shaping, such as initial or final variants in connected
+      scripts.
+    </para>
+    <para>
+      <literal>HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES</literal>
+      tells HarfBuzz not to hide glyphs with the
+      <literal>Default_Ignorable</literal> property in Unicode. This 
+      property designates control characters and other non-printing
+      code points, such as joiners and variation selectors. Normally
+      HarfBuzz replaces them in the output buffer with zero-width
+      space glyphs (using the "invisible glyph" property discussed
+      above); setting this flag causes them to be printed, which can
+      be helpful for troubleshooting.
+    </para>
+    <para>
+      Conversely, setting the
+      <literal>HB_BUFFER_FLAG_REMOVE_DEFAULT_IGNORABLES</literal> flag
+      tells HarfBuzz to remove <literal>Default_Ignorable</literal>
+      glyphs from the output buffer entirely. Finally, setting the
+      <literal>HB_BUFFER_FLAG_DO_NOT_INSERT_DOTTED_CIRCLE</literal>
+      flag tells HarfBuzz not to insert the dotted-circle glyph
+      (<literal>U+25CC</literal>, "&#x25CC;"), which is normally
+      inserted into buffer output when broken character sequences are
+      encountered (such as combining marks that are not attached to a
+      base character).

+  <section id="customizing-unicode-functions">
+    <title>Customizing Unicode functions</title>
+    <para>
+      HarfBuzz requires some simple functions for accessing
+      information from the Unicode Character Database (such as the
+      <literal>General_Category</literal> (gc) and
+      <literal>Script</literal> (sc) properties) that is useful
+      for shaping, as well as some useful operations like composing and
+      decomposing code points.
+    </para>
+    <para>
+      HarfBuzz includes its own internal, lightweight set of Unicode
+      functions. At build time, it is also possible to compile support
+      for some other options, such as the Unicode functions provided
+      by GLib or the International Components for Unicode (ICU)
+      library. Generally, this option is only of interest for client
+      programs that have specific integration requirements or that do
+      a significant amount of customization.
+    </para>
+    <para>
+      If your program has access to other Unicode functions, however,
+      such as through a system library or application framework, you
+      might prefer to use those instead of the built-in
+      options. HarfBuzz supports this by implementing its Unicode
+      functions as a set of virtual methods that you can replace —
+      without otherwise affecting HarfBuzz's functionality.
+    </para>
+    <para>
+      The Unicode functions are specified in a structure called
+      <literal>unicode_funcs</literal> which is attached to each
+      buffer. But even though <literal>unicode_funcs</literal> is
+      associated with a <type>hb_buffer_t</type>, the functions
+      themselves are called by other HarfBuzz APIs that access
+      buffers, so it would be unwise for you to hook different
+      functions into different buffers.
+    </para>
+    <para>
+      In addition, you can mark your <literal>unicode_funcs</literal>
+      as immutable by calling
+      <function>hb_unicode_funcs_make_immutable (ufuncs)</function>.
+      This is especially useful if your code is a
+      library or framework that will have its own client programs. By
+      marking your Unicode function choices as immutable, you prevent
+      your own client programs from changing the
+      <literal>unicode_funcs</literal> configuration and introducing
+      inconsistencies and errors downstream.
+    </para>
+    <para>
+      You can retrieve the Unicode-functions configuration for

+    <title>Clusters and shaping</title>
+    <para>
+      In text shaping, a <emphasis>cluster</emphasis> is a sequence of
+      characters that needs to be treated as a single, indivisible
+      unit. A single letter or symbol can be a cluster of its
+      own. Other clusters correspond to longer subsequences of the
+      input code points &mdash; such as a ligature or conjunct form
+      &mdash; and require the shaper to ensure that the cluster is not
+      broken during the shaping process.
+    </para>
+    <para>
+      A cluster is distinct from a <emphasis>grapheme</emphasis>,
+      which is the smallest unit of meaning in a writing system or
+      script.
+    </para>
+    <para>
+      The definitions of the two terms are similar. However, clusters
+      are only relevant for script shaping and glyph layout. In
+      contrast, graphemes are a property of the underlying script, and
+      are of interest when client programs implement orthographic 
+      or linguistic functionality.
+    </para>
+    <para>
+      For example, two individual letters are often two separate
+      graphemes. When two letters form a ligature, however, they
+      combine into a single glyph. They are then part of the same
+      cluster and are treated as a unit by the shaping engine &mdash;
+      even though the two original, underlying letters remain separate
+      graphemes.
+    </para>
+    <para>
+      HarfBuzz is concerned with clusters, <emphasis>not</emphasis>
+      with graphemes &mdash; although client programs using HarfBuzz
+      may still care about graphemes for other reasons from time to time.
+    </para>
+    <para>
+      During the shaping process, there are several shaping operations
+      that may merge adjacent characters (for example, when two code
+      points form a ligature or a conjunct form and are replaced by a
+      single glyph) or split one character into several (for example,
+      when decomposing a code point through the
+      <literal>ccmp</literal> feature). Operations like these alter
+      clusters; HarfBuzz tracks the changes to ensure that no clusters
+      get lost or broken during shaping. 
+    </para>
+    <para>
+      HarfBuzz records cluster information independently from how
+      shaping operations affect the individual glyphs returned in an
+      output buffer. Consequently, a client program using HarfBuzz can
+      utilize the cluster information to implement features such as:
+    </para>
+    <itemizedlist>
+      <listitem>
+	<para>

+    <title>Working with HarfBuzz clusters</title>
+    <para>
+      When you add text to a HarfBuzz buffer, each code point must be
+      assigned a <emphasis>cluster value</emphasis>.
+    </para>
+    <para>
+      This cluster value is an arbitrary number; HarfBuzz uses it only
+      to distinguish between clusters. Many client programs will use
+      the index of each code point in the input text stream as the
+      cluster value. This is for the sake of convenience; the actual
+      value does not matter.
+    </para>
+    <para>
+      Some of the shaping operations performed by HarfBuzz &mdash;
+      such as reordering, composition, decomposition, and substitution
+      &mdash; may alter the cluster values of some characters. The
+      final cluster values in the buffer at the end of the shaping
+      process will indicate to client programs which subsequences of
+      glyphs represent a cluster and, therefore, must not be
+      separated.
+    </para>
+    <para>
+      In addition, client programs can query the final cluster values
+      to discern other potentially important information about the
+      glyphs in the output buffer (such as whether or not a ligature
+      was formed).
+    </para>
+    <para>
+      For example, if the initial sequence of cluster values was:
+    </para>
+    <programlisting>
+      0,1,2,3,4
+    </programlisting>
+    <para>
+      and the final sequence of cluster values is:
+    </para>
+    <programlisting>
+      0,0,3,3
+    </programlisting>
+    <para>
+      then there are two clusters in the output buffer: the first
+      cluster includes the first two glyphs, and the second cluster
+      includes the third and fourth glyphs. It is also evident that a
+      ligature or conjunct has been formed, because there are fewer
+      glyphs in the output buffer (four) than there were code points
+      in the input buffer (five).
+    </para>
+    <para>
+      Although client programs using HarfBuzz are free to assign
+      initial cluster values in any manner they choose to, HarfBuzz
+      does offer some useful guarantees if the cluster values are
+      assigned in a monotonic (either non-decreasing or non-increasing)
+      order.
+    </para>
+    <para>
+      For buffers in the left-to-right (LTR)
+      or top-to-bottom (TTB) text flow direction,
+      HarfBuzz will preserve the monotonic property: client programs
+      are guaranteed that monotonically increasing initial cluster
+      values will be returned as monotonically increasing final
+      cluster values.
+    </para>
+    <para>
+      For buffers in the right-to-left (RTL)
+      or bottom-to-top (BTT) text flow direction,
+      the directionality of the buffer itself is reversed for final
+      output as a matter of design. Therefore, HarfBuzz inverts the
+      monotonic property: client programs are guaranteed that
+      monotonically increasing initial cluster values will be
+      returned as monotonically <emphasis>decreasing</emphasis> final
+      cluster values.
+    </para>
+    <para>
+      Client programs can adjust how HarfBuzz handles clusters during
+      shaping by setting the
+      <literal>cluster_level</literal> of the
+      buffer. HarfBuzz offers three <emphasis>levels</emphasis> of
+      clustering support for this property:
+    </para>
+    <itemizedlist>
+      <listitem>
+	<para><emphasis>Level 0</emphasis> is the default and
+	reproduces the behavior of the old HarfBuzz library.
+	</para>
+	<para>
+	  The distinguishing feature of level 0 behavior is that, at
+	  the beginning of processing the buffer, all code points that
+	  are categorized as <emphasis>marks</emphasis>,
+	  <emphasis>modifier symbols</emphasis>, or
+	  <emphasis>Emoji extended pictographic</emphasis> modifiers,
+	  as well as the <emphasis>Zero Width Joiner</emphasis> and
+	  <emphasis>Zero Width Non-Joiner</emphasis> code points, are
+	  assigned the cluster value of the closest preceding code
+	  point from <emphasis>different</emphasis> category. 
+	</para>
+	<para>
+	  In essence, whenever a base character is followed by a mark
+	  character or a sequence of mark characters, those marks are
+	  reassigned to the same initial cluster value as the base
+	  character. This reassignment is referred to as
+	  "merging" the affected clusters. This behavior is based on
+	  the Grapheme Cluster Boundary specification in <ulink
+	  url="https://www.unicode.org/reports/tr29/#Regex_Definitions">Unicode
+	  Technical Report 29</ulink>.
+	</para>
+	<para>
+	  Client programs can specify level 0 behavior for a buffer by
+	  setting its <literal>cluster_level</literal> to
+	  <literal>HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES</literal>. 
+	</para>
+      </listitem>
+      <listitem>
+	<para>
+	  <emphasis>Level 1</emphasis> tweaks the old behavior
+	  slightly to produce better results. Therefore, level 1
+	  clustering is recommended for code that is not required to
+	  implement backward compatibility with the old HarfBuzz.
+	</para>
+	<para>
+	  Level 1 differs from level 0 by not merging the 
+	  clusters of marks and other modifier code points with the
+	  preceding "base" code point's cluster. By preserving the
+	  separate cluster values of these marks and modifier code
+	  points, script shapers can perform additional operations
+	  that might lead to improved results (for example, reordering
+	  a sequence of marks).
+	</para>
+	<para>
+	  Client programs can specify level 1 behavior for a buffer by
+	  setting its <literal>cluster_level</literal> to
+	  <literal>HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS</literal>. 
+	</para>
+      </listitem>
+      <listitem>
+	<para>
+	  <emphasis>Level 2</emphasis> differs significantly in how it
+	  treats cluster values. In level 2, HarfBuzz never merges
+	  clusters.
+	</para>
+	<para>
+	  This difference can be seen most clearly when HarfBuzz processes
+	  ligature substitutions and glyph decompositions. In level 0 
+	  and level 1, ligatures and glyph decomposition both involve
+	  merging clusters; in level 2, neither of these operations
+	  triggers a merge.
+	</para>
+	<para>
+	  Client programs can specify level 2 behavior for a buffer by
+	  setting its <literal>cluster_level</literal> to
+	  <literal>HB_BUFFER_CLUSTER_LEVEL_CHARACTERS</literal>. 
+	</para>
+      </listitem>
+    </itemizedlist>
+    <para>
+      As mentioned earlier, client programs using HarfBuzz often
+      assign initial cluster values in a buffer by reusing the indices
+      of the code points in the input text. This gives a sequence of
+      cluster values that is monotonically increasing (for example,
+      0,1,2,3,4). 
+    </para>
+    <para>
+      It is not <emphasis>required</emphasis> that the cluster values
+      in a buffer be monotonically increasing. However, if the initial
+      cluster values in a buffer are monotonic and the buffer is
+      configured to use cluster level 0 or 1, then HarfBuzz
+      guarantees that the final cluster values in the shaped buffer

+    <para>
+      In levels 0 and 1, HarfBuzz implements the following conceptual
+      model for cluster values:
+    </para>
+    <itemizedlist spacing="compact">
+      <listitem>
+	<para>
+          If the sequence of input cluster values is monotonic, the

+    <para>
+      In practice, this model offers several benefits. Assuming that

+    <para>
+      The functionality, guarantees, and benefits of level 0 and level
+      1 behavior can be seen with some examples. First, let us examine
+      what happens with cluster values when shaping involves cluster
+      merging with ligatures and decomposition.
+    </para>
+
+    <para>
+      Let's say we start with the following character sequence (top row) and
+      initial cluster values (bottom row):
+    </para>
+    <programlisting>
+      A,B,C,D,E
+      0,1,2,3,4
+    </programlisting>
+    <para>
+      During shaping, HarfBuzz maps these characters to glyphs from
+      the font. For simplicity, let us assume that each character maps
+      to the corresponding, identical-looking glyph:
+    </para>
+    <programlisting>
+      A,B,C,D,E
+      0,1,2,3,4
+    </programlisting>
+    <para>
+      Now if, for example, <literal>B</literal> and <literal>C</literal>
+      form a ligature, then the clusters to which they belong
+      &quot;merge&quot;. This merged cluster takes for its cluster
+      value the minimum of all the cluster values of the clusters that
+      went in to the ligature. In this case, we get:
+    </para>
+    <programlisting>
+      A,BC,D,E
+      0,1 ,3,4
+    </programlisting>
+    <para>
+      because 1 is the minimum of the set {1,2}, which were the
+      cluster values of <literal>B</literal> and
+      <literal>C</literal>. 
+    </para>
+    <para>
+      Next, let us say that the <literal>BC</literal> ligature glyph
+      decomposes into three components, and <literal>D</literal> also
+      decomposes into two components. Whenever a cluster decomposes,
+      its components each inherit the cluster value of their parent: 
+    </para>
+    <programlisting>
+      A,BC0,BC1,BC2,D0,D1,E
+      0,1  ,1  ,1  ,3 ,3 ,4
+    </programlisting>
+    <para>
+      Next, if <literal>BC2</literal> and <literal>D0</literal> form a
+      ligature, then their clusters (cluster values 1 and 3) merge into
+      <literal>min(1,3) = 1</literal>:
+    </para>
+    <programlisting>
+      A,BC0,BC1,BC2D0,D1,E
+      0,1  ,1  ,1    ,1 ,4
+    </programlisting>
+    <para>
+      Note that the entirety of cluster 3 merges into cluster 1, not
+      just the <literal>D0</literal> glyph. This reflects the fact
+      that the cluster <emphasis>must</emphasis> be treated as an
+      indivisible unit.
+    </para>
+    <para>
+      At this point, cluster 1 means: the character sequence
+      <literal>BCD</literal> is represented by glyphs
+      <literal>BC0,BC1,BC2D0,D1</literal> and cannot be broken down any
+      further.
+    </para>
+  </section>
+  <section id="reordering-in-levels-0-and-1">
+    <title>Reordering in levels 0 and 1</title>
+    <para>
+      Another common operation in the more complex shapers is glyph
+      reordering. In order to maintain a monotonic cluster sequence
+      when glyph reordering takes place, HarfBuzz merges the clusters
+      of everything in the reordering sequence.
+    </para>
+    <para>
+      For example, let us again start with the character sequence (top
+      row) and initial cluster values (bottom row):
+    </para>
+    <programlisting>
+      A,B,C,D,E
+      0,1,2,3,4
+    </programlisting>
+    <para>
+      If <literal>D</literal> is reordered to the position immediately
+      before <literal>B</literal>, then HarfBuzz merges the
+      <literal>B</literal>, <literal>C</literal>, and
+      <literal>D</literal> clusters &mdash; all the clusters between
+      the final position of the reordered glyph and its original
+      position. This means that we get:
+    </para>
+    <programlisting>
+      A,D,B,C,E
+      0,1,1,1,4
+    </programlisting>
+    <para>
+      as the final cluster sequence.
+    </para>
+    <para>
+      Merging this many clusters is not ideal, but it is the only
+      sensible way for HarfBuzz to maintain the guarantee that the
+      sequence of cluster values remains monotonic and to retain the
+      true relationship between glyphs and characters.
+    </para>
+  </section>
+  <section id="the-distinction-between-levels-0-and-1">
+    <title>The distinction between levels 0 and 1</title>
+    <para>
+      The preceding examples demonstrate the main effects of using
+      cluster levels 0 and 1. The only difference between the two
+      levels is this: in level 0, at the very beginning of the shaping
+      process, HarfBuzz merges the cluster of each base character
+      with the clusters of all Unicode marks (combining or not) and
+      modifiers that follow it.
+    </para>
+    <para>
+      For example, let us start with the following character sequence
+      (top row) and accompanying initial cluster values (bottom row):
+    </para>
+    <programlisting>
+      A,acute,B
+      0,1    ,2
+    </programlisting>
+    <para>
+      The <literal>acute</literal> is a Unicode mark. If HarfBuzz is
+      using cluster level 0 on this sequence, then the
+      <literal>A</literal> and <literal>acute</literal> clusters will
+      merge, and the result will become:
+    </para>
+    <programlisting>
+      A,acute,B
+      0,0    ,2
+    </programlisting>
+    <para>
+      This merger is performed before any other script-shaping
+      steps.
+    </para>
+    <para>
+      This initial cluster merging is the default behavior of the
+      Windows shaping engine, and the old HarfBuzz codebase copied
+      that behavior to maintain compatibility. Consequently, it has
+      remained the default behavior in the new HarfBuzz codebase.
+    </para>
+    <para>
+      But this initial cluster-merging behavior makes it impossible
+      for client programs to implement some features (such as to
+      color diacritic marks differently from their base
+      characters). That is why, in level 1, HarfBuzz does not perform
+      the initial merging step.
+    </para>
+    <para>
+      For client programs that rely on HarfBuzz cluster values to
+      perform cursor positioning, level 0 is more convenient. But
+      relying on cluster boundaries for cursor positioning is wrong: cursor
+      positions should be determined based on Unicode grapheme
+      boundaries, not on shaping-cluster boundaries. As such, using
+      level 1 clustering behavior is recommended. 
+    </para>
+    <para>
+      One final facet of levels 0 and 1 is worth noting. HarfBuzz
+      currently does not allow any
+      <emphasis>multiple-substitution</emphasis> GSUB lookups to 
+      replace a glyph with zero glyphs (in other words, to delete a
+      glyph).
+    </para>
+    <para>
+      But, in some other situations, glyphs can be deleted. In
+      those cases, if the glyph being deleted is the last glyph of its
+      cluster, HarfBuzz makes sure to merge the deleted glyph's
+      cluster with a neighboring cluster.
+    </para>
+    <para>
+      This is done primarily to make sure that the starting cluster of the
+      text always has the cluster index pointing to the start of the text
+      for the run; more than one client program currently relies on this
+      guarantee.
+    </para>
+    <para>
+      Incidentally, Apple's CoreText does something different to
+      maintain the same promise: it inserts a glyph with id 65535 at
+      the beginning of the glyph string if the glyph corresponding to
+      the first character in the run was deleted. HarfBuzz might do
+      something similar in the future.
+    </para>
+  </section>
+  <section id="level-2">
+    <title>Level 2</title>
+    <para>
+      HarfBuzz's level 2 cluster behavior uses a significantly
+      different model than that of level 0 and level 1.
+    </para>
+    <para>
+      The level 2 behavior is easy to describe, but it may be
+      difficult to understand in practical terms. In brief, level 2 
+      performs no merging of clusters whatsoever.
+    </para>
+    <para>
+      This means that there is no initial base-and-mark merging step
+      (as is done in level 0), and it means that reordering moves and
+      ligature substitutions do not trigger a cluster merge.
+    </para>
+    <para>
+      Only one shaping operation directly affects clusters when using
+      level 2:
+    </para>
+    <itemizedlist>
+      <listitem>
+	<para>
+	  When a cluster <emphasis>decomposes</emphasis>, all of the
+	  resulting child clusters inherit as their cluster value the

+      </listitem>
+    </itemizedlist>
+    <para>
+      When glyphs do form a ligature (or when some other feature
+      substitutes multiple glyphs with one glyph) the cluster value
+      of the first glyph is retained as the cluster value for the
+      resulting ligature.
+    </para>
+    <para>
+      This occurrence sounds similar to a cluster merge, but it is
+      different. In particular, no subsequent characters &mdash;
+      including marks and modifiers &mdash; are affected. They retain
+      their previous cluster values. 
+    </para>
+    <para>
+      Level 2 cluster behavior is ultimately less complex than level 0
+      or level 1, but there are several cases for which processing
+      cluster values produced at level 2 may be tricky.

+    <para>
+      In the previous chapter, we saw how to set up a buffer and fill
+      it with text as Unicode code points. In order to shape this
+      buffer text with HarfBuzz, you will need also need a font
+      object.
+    </para>
+    <para>
+      HarfBuzz provides abstractions to help you cache and reuse the
+      heavier parts of working with binary fonts, so we will look at
+      how to do that. We will also look at how to work with the
+      FreeType font-rendering library and at how you can customize
+      HarfBuzz to work with other libraries.
+    </para>
+    <para>
+      Finally, we will look at how to work with OpenType variable
+      fonts, the latest update to the OpenType font format, and at
+      some other recent additions to OpenType.
+    </para>
+
+  <section id="fonts-and-faces-objects">
+    <title>Font and face objects</title>
+    <para>
+      The outcome of shaping a run of text depends on the contents of
+      a specific font file (such as the substitutions and positioning
+      moves in the 'GSUB' and 'GPOS' tables), so HarfBuzz makes
+      accessing those internals fast.
+    </para>
+    <para>
+      An <type>hb_face_t</type> represents a <emphasis>face</emphasis>
+      in HarfBuzz. This data type is a wrapper around an
+      <type>hb_blob_t</type> blob that holds the contents of a binary
+      font file. Since HarfBuzz supports TrueType Collections and
+      OpenType Collections (each of which can include multiple
+      typefaces), a HarfBuzz face also requires an index number
+      specifying which typeface in the file you want to use. Most of
+      the font files you will encounter in the wild include just a
+      single face, however, so most of the time you would pass in
+      <literal>0</literal> as the index when you create a face:
+    </para>
+    <programlisting language="C">
+      hb_blob_t* blob = hb_blob_create_from_file(file);
+      ...
+      hb_face_t* face = hb_face_create(blob, 0);
+    </programlisting>
+    <para>
+      On its own, a face object is not quite ready to use for
+      shaping. The typeface must be set to a specific point size in
+      order for some details (such as hinting) to work. In addition,
+      if the font file in question is an OpenType Variable Font, then
+      you may need to specify one or variation-axis settings (or a
+      named instance) in order to get the output you need.
+    </para>
+    <para>
+      In HarfBuzz, you do this by creating a <emphasis>font</emphasis>
+      object from your face.
+    </para>
+    <para>
+      Font objects also have the advantage of being considerably
+      lighter-weight than face objects (remember that a face contains
+      the contents of a binary font file mapped into memory). As a
+      result, you can cache and reuse a font object, but you could
+      also create a new one for each additional size you needed.
+      Creating new fonts incurs some additional overhead, of course,
+      but whether or not it is excessive is your call in the end. In
+      contrast, face objects are substantially larger, and you really
+      should cache them and reuse them whenever possible.
+    </para>
+    <para>
+      You can create a font object from a face object:
+    </para>
+    <programlisting language="C">
+      hb_font_t* hb_font = hb_font_create(hb_face);
+    </programlisting>
+    <para>
+      After creating a font, there are a few properties you should
+      set. Many fonts enable and disable hints based on the size it
+      is used at, so setting this is important for font
+      objects. <function>hb_font_set_ppem(font, x_ppem,
+      y_ppem)</function> sets the pixels-per-EM value of the font. You
+      can also set the point size of the font with
+      <function>hb_font_set_ptem(font, ptem)</function>. HarfBuzz uses the
+      industry standard 72 points per inch.
+    </para>
+    <para>
+      HarfBuzz lets you specify the degree subpixel precision you want
+      through a scaling factor. You can set horizontal and
+      vertical scaling factors on the
+      font by calling <function>hb_font_set_scale(font, x_scale,
+      y_scale)</function>. 
+    </para>
+    <para>
+      There may be times when you are handed a font object and need to

+    </programlisting>
+    <para>
+      You can also create a font object from an existing font object
+      using the <function>hb_font_create_sub_font()</function>
+      function. This creates a child font object that is initiated
+      with the same attributes as its parent; it can be used to
+      quickly set up a new font for the purpose of overriding a specific

+      All face objects and font objects are lifecycle-managed by

+      count with <function>hb_face_reference(face)</function> and
+      decrease it with
+      <function>hb_face_destroy(face)</function>. Likewise, you
+      increase the reference count on a font with

+      with <function>hb_font_destroy(font)</function>.

+      During shaping, HarfBuzz frequently needs to query font objects
+      to get at the contents and parameters of the glyphs in a font
+      file. It includes a built-in set of functions that is tailored
+      to working with OpenType fonts. However, as was the case with
+      Unicode functions in the buffers chapter, HarfBuzz also wants to
+      make it easy for you to assign a substitute set of font
+      functions if you are developing a program to work with a library
+      or platform that provides its own font functions. 
+    </para>
+    <para>
+      Therefore, the HarfBuzz API defines a set of virtual
+      methods for accessing font-object properties, and you can
+      replace the defaults with your own selections without
+      interfering with the shaping process. Each font object in
+      HarfBuzz includes a structure called
+      <literal>font_funcs</literal> that serves as a vtable for the
+      font object. The virtual methods in
+      <literal>font_funcs</literal> are:

+      Font-functions structures can be reused for multiple font

+      programs from changing the configuration and introducing
+      inconsistencies and errors downstream.

+    <title>Font objects and HarfBuzz's native OpenType implementation</title>
+    <para>
+      By default, whenever HarfBuzz creates a font object, it will
+      configure the font to use a built-in set of font functions that
+      supports contemporary OpenType font internals. If you want to
+      work with OpenType or TrueType fonts, you should be able to use
+      these functions without difficulty.
+    </para>
+    <para>
+      Many of the methods in the font-functions structure deal with
+      the fundamental properties of glyphs that are required for
+      shaping text: extents (the maximums and minimums on each axis),
+      origins (the <literal>(0,0)</literal> coordinate point which
+      glyphs are drawn in reference to), and advances (the amount that
+      the cursor needs to be moved after drawing each glyph, including
+      any empty space for the glyph's side bearings).
+    </para>
+    <para>
+      As you can see in the list of functions, there are separate "horizontal"
+      and "vertical" variants depending on whether the text is set in
+      the horizontal or vertical direction. For some scripts, fonts
+      that are designed to support text set horizontally or vertically (for
+      example, in Japanese) may include metrics for both text
+      directions. When fonts don't include this information, HarfBuzz
+      does its best to transform what the font provides.
+    </para>
+    <para>
+      In addition to the direction-specific functions, HarfBuzz
+      provides some higher-level functions for fetching information
+      like extents and advances for a glyph. If you call
+    </para>
+    <programlisting language="C">
+      hb_font_get_glyph_advance_for_direction(font, direction, extents);
+    </programlisting>
+    <para>
+      then you can provide any <type>hb_direction_t</type> as the
+      <parameter>direction</parameter> parameter, and HarfBuzz will
+      use the correct function variant for the text direction. There
+      are similar higher-level versions of the functions for fetching
+      extents, origin coordinates, and contour-point
+      coordinates. There are also addition and subtraction functions
+      for moving points with respect to the origin.
+    </para>
+    <para>
+      There are also methods for fetching the glyph ID that
+      corresponds to a Unicode code point (possibly when followed by a
+      variation-selector code point), fetching the glyph name from the
+      font, and fetching the glyph ID that corresponds to a glyph name
+      you already have.
+    </para>
+    <para>
+      HarfBuzz also provides functions for converting between glyph
+      names and string
+      variables. <function>hb_font_glyph_to_string(font, glyph, s,
+      size)</function> retrieves the name for the glyph ID
+      <parameter>glyph</parameter> from the font object. It generates a
+      generic name of the form <literal>gidDDD</literal> (where DDD is
+      the glyph index) if there is no name for the glyph in the
+      font. The <function>hb_font_glyph_from_string(font, s, len,
+      glyph)</function> takes an input string <parameter>s</parameter>
+      and looks for a glyph with that name in the font, returning its
+      glyph ID in the <parameter>glyph</parameter>
+      output parameter. It automatically parses
+      <literal>gidDDD</literal> and <literal>uniUUUU</literal> strings.

+    <title>Working with OpenType Variable Fonts</title>
+    <para>
+      If you are working with OpenType Variable Fonts, there are a few
+      additional functions you should use to specify the
+      variation-axis settings of your font object. Without doing so,
+      your variable font's font object can still be used, but only at
+      the default setting for every axis (which, of course, is
+      sometimes what you want, but does not cover general usage).
+    </para>
+    <para>
+      HarfBuzz manages variation settings in the
+      <type>hb_variation_t</type> data type, which holds a <property>tag</property> for the
+      variation-axis identifier tag and a <property>value</property> for its
+      setting. You can retrieve the list of variation axes in a font
+      binary from the face object (not from a font object, notably) by
+      calling <function>hb_ot_var_get_axis_count(face)</function> to
+      find the number of axes, then using
+      <function>hb_ot_var_get_axis_infos()</function> to collect the 
+      axis structures:
+    </para>
+    <programlisting language="C">
+      axes = hb_ot_var_get_axis_count(face);
+      ...
+      hb_ot_var_get_axis_infos(face, 0, axes, axes_array);
+    </programlisting>
+    <para>
+      For each axis returned in the array, you can can access the
+      identifier in its <property>tag</property>. HarfBuzz also has
+      tag definitions predefined for the five standard axes specified
+      in OpenType (<literal>ital</literal> for italic,
+      <literal>opsz</literal> for optical size,
+      <literal>slnt</literal> for slant, <literal>wdth</literal> for
+      width, and <literal>wght</literal> for weight). Each axis also
+      has a <property>min_value</property>, a
+      <property>default_value</property>, and a <property>max_value</property>.
+    </para>
+    <para>
+      To set your font object's variation settings, you call the
+      <function>hb_font_set_variations()</function> function with an
+      array of <type>hb_variation_t</type> variation settings. Let's
+      say our font has weight and width axes. We need to specify each
+      of the axes by tag and assign a value on the axis:
+    </para>
+    <programlisting language="C">
+      unsigned int variation_count = 2;
+      hb_variation_t variation_data[variation_count];
+      variation_data[0].tag = HB_OT_TAG_VAR_AXIS_WIDTH;
+      variation_data[1].tag = HB_OT_TAG_VAR_AXIS_WEIGHT;
+      variation_data[0].value = 80;
+      variation_data[1].value = 750;
+      ...
+      hb_font_set_variations(font, variation_data, variation_count);
+    </programlisting>
+    <para>
+      That should give us a slightly condensed font ("normal" on the
+      <literal>wdth</literal> axis is 100) at a noticeably bolder
+      weight ("regular" is 400 on the <literal>wght</literal> axis).
+    </para>
+    <para>
+      In practice, though, you should always check that the value you
+      want to set on the axis is within the
+      [<property>min_value</property>,<property>max_value</property>]
+      range actually implemented in the font's variation axis. After
+      all, a font might only provide lighter-than-regular weights, and
+      setting a heavier value on the <literal>wght</literal> axis will
+      not change that. 
+    </para>
+    <para>
+      Once your variation settings are specified on your font object,
+      however, shaping with a variable font is just like shaping a
+      static font.
