dictates one aspect of how HarfBuzz will treat non-base characters
during shaping.

In @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES, non-base
characters are merged into the cluster of the base character that precedes them.

In @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS, non-base characters are initially
assigned their own cluster values, which are not merged into preceding base
clusters. This allows HarfBuzz to perform additional operations like reorder
sequences of adjacent marks.

@HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES is the default, because it maintains
backward compatibility with older versions of HarfBuzz. New client programs that
do not need to maintain such backward compatibility are recommended to use
@HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS instead of the default.</doc>

will be set to the Unicode script of the first character in

Next, if buffer direction is not set (ie. is #HB_DIRECTION_INVALID),
it will be set to the natural horizontal direction of the
buffer script as returned by hb_script_get_horizontal_direction().
If hb_script_get_horizontal_direction() returns #HB_DIRECTION_INVALID,

Finally, if buffer language is not set (ie. is #HB_LANGUAGE_INVALID),
it will be set to the process's default language as returned by
hb_language_get_default().  This may change in the future by
taking buffer script into consideration when choosing a language.

useful for showing the contents of the buffer, for example during debugging.
There are currently two supported serialization formats:

## text
A human-readable, plain text format.
The serialized glyphs will look something like:

```
[uni0651=0@518,0+0|uni0628=0+1897]
```

- The serialized glyphs are delimited with `[` and `]`.
- Glyphs are separated with `|`
- Each glyph starts with glyph name, or glyph index if
  #HB_BUFFER_SERIALIZE_FLAG_NO_GLYPH_NAMES flag is set. Then,
  - If #HB_BUFFER_SERIALIZE_FLAG_NO_CLUSTERS is not set, `=` then #hb_glyph_info_t.cluster.
  - If #HB_BUFFER_SERIALIZE_FLAG_NO_POSITIONS is not set, the #hb_glyph_position_t in the format:
    - If both #hb_glyph_position_t.x_offset and #hb_glyph_position_t.y_offset are not 0, `@x_offset,y_offset`. Then,
    - `+x_advance`, then `,y_advance` if #hb_glyph_position_t.y_advance is not 0. Then,
  - If #HB_BUFFER_SERIALIZE_FLAG_GLYPH_EXTENTS is set, the #hb_glyph_extents_t in the format `&lt;x_bearing,y_bearing,width,height&gt;`

## json
A machine-readable, structured format.
The serialized glyphs will look something like:

```
[{"g":"uni0651","cl":0,"dx":518,"dy":0,"ax":0,"ay":0},
{"g":"uni0628","cl":0,"dx":0,"dy":0,"ax":1897,"ay":0}]
```

Each glyph is a JSON object, with the following properties:
- `g`: the glyph name or glyph index if
  #HB_BUFFER_SERIALIZE_FLAG_NO_GLYPH_NAMES flag is set.
- `cl`: #hb_glyph_info_t.cluster if
  #HB_BUFFER_SERIALIZE_FLAG_NO_CLUSTERS is not set.
- `dx`,`dy`,`ax`,`ay`: #hb_glyph_position_t.x_offset, #hb_glyph_position_t.y_offset,
   #hb_glyph_position_t.x_advance and #hb_glyph_position_t.y_advance
   respectively, if #HB_BUFFER_SERIALIZE_FLAG_NO_POSITIONS is not set.
- `xb`,`yb`,`w`,`h`: #hb_glyph_extents_t.x_bearing, #hb_glyph_extents_t.y_bearing,
   #hb_glyph_extents_t.width and #hb_glyph_extents_t.height respectively if
   #HB_BUFFER_SERIALIZE_FLAG_GLYPH_EXTENTS is set.</doc>

Languages are crucial for selecting which OpenType feature to apply to the

are orthogonal to the scripts, and though they are related, they are
different concepts and should not be confused with each other.

The format for specifying feature strings follows. All valid CSS
font-feature-settings values other than 'normal' and the global values are
also accepted, though not documented below. CSS string escapes are not
supported.

The range indices refer to the positions between Unicode characters. The
position before the first character is always 0.

The format is Python-esque.  Here is how it all works:

&lt;informaltable pgwide='1' align='left' frame='none'&gt;
&lt;tgroup cols='5'&gt;
&lt;thead&gt;
&lt;row&gt;&lt;entry&gt;Syntax&lt;/entry&gt;    &lt;entry&gt;Value&lt;/entry&gt; &lt;entry&gt;Start&lt;/entry&gt; &lt;entry&gt;End&lt;/entry&gt;&lt;/row&gt;
&lt;/thead&gt;
&lt;tbody&gt;
&lt;row&gt;&lt;entry&gt;Setting value:&lt;/entry&gt;&lt;/row&gt;
&lt;row&gt;&lt;entry&gt;kern&lt;/entry&gt;      &lt;entry&gt;1&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;      &lt;entry&gt;∞&lt;/entry&gt;   &lt;entry&gt;Turn feature on&lt;/entry&gt;&lt;/row&gt;
&lt;row&gt;&lt;entry&gt;+kern&lt;/entry&gt;     &lt;entry&gt;1&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;      &lt;entry&gt;∞&lt;/entry&gt;   &lt;entry&gt;Turn feature on&lt;/entry&gt;&lt;/row&gt;
&lt;row&gt;&lt;entry&gt;-kern&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;      &lt;entry&gt;∞&lt;/entry&gt;   &lt;entry&gt;Turn feature off&lt;/entry&gt;&lt;/row&gt;

access `size` member of FT_Face unconditionally.&lt;/note&gt;

This variant of the function does not provide any life-cycle management.

Most client programs should use hb_ft_font_create_referenced()
instead.

If you know you have valid reasons not to use hb_ft_font_create_referenced(),
then it is the client program's responsibility to destroy @ft_face
after the #hb_font_t font object has been destroyed.

HarfBuzz will use the @destroy callback on the #hb_font_t font object
if it is supplied when you use this function. However, even if @destroy
is provided, it is the client program's responsibility to destroy @ft_face,
and it is the client program's responsibility to ensure that @ft_face is
destroyed only after the #hb_font_t font object has been destroyed.</doc>

Regarding these various memory-modes:

- In no case shall the HarfBuzz client modify memory
  that is passed to HarfBuzz in a blob.  If there is
  any such possibility, @HB_MEMORY_MODE_DUPLICATE should be used
  such that HarfBuzz makes a copy immediately,

- Use @HB_MEMORY_MODE_READONLY otherwise, unless you really really
  really know what you are doing,

- @HB_MEMORY_MODE_WRITABLE is appropriate if you really made a
  copy of data solely for the purpose of passing to
  HarfBuzz and doing that just once (no reuse!),

- If the font is mmap()ed, it's okay to use
  @HB_MEMORY_READONLY_MAY_MAKE_WRITABLE, however, using that mode
  correctly is very tricky.  Use @HB_MEMORY_MODE_READONLY instead.</doc>

The complete length of the decomposition will be returned.

If @u has no compatibility decomposition, zero should be returned.

The Unicode standard guarantees that a buffer of length #HB_UNICODE_MAX_DECOMPOSITION_LEN codepoints will always be sufficient for any
compatibility decomposition plus an terminating value of 0.  Consequently, @decompose must be allocated by the caller to be at least this length.  Implementations
of this function type must ensure that they do not write past the provided array.</doc>
