Platform identifier codes.
- `APPLE_UNICODE`: Used by Apple to indicate a Unicode character map
and/or name entry. See `TT_APPLE_ID` for corresponding ‘encoding_id’
values. Note that name entries in this format are coded as
big-endian UCS-2 character codes only.
- `MACINTOSH`: Used by Apple to indicate a MacOS-specific charmap
and/or name entry. See `TT_MAC_ID` for corresponding ‘encoding_id’
values. Note that most TrueType fonts contain an Apple roman charmap
to be usable on MacOS systems (even if they contain a Microsoft
charmap as well).
- `ISO`: This value was used to specify ISO/IEC 10646 charmaps. It is
however now deprecated. See `TT_ISO_ID` for a list of
corresponding ‘encoding_id’ values.
- `MICROSOFT`: Used by Microsoft to indicate Windows-specific
charmaps. See `TT_MS_ID` for a list of corresponding ‘encoding_id’
values. Note that most fonts contain a Unicode charmap using
(`TT_PLATFORM.MICROSOFT`, `TT_MS_ID.UNICODE_CS`).
- `CUSTOM`: Used to indicate application-specific charmaps.
- `ADOBE`: This value isn't part of any font format specification, but
is used by FreeType to report Adobe-specific charmaps in an
`CharMap` object. See `TT_ADOBE_ID`.

Apple-specific encoding values.
- `DEFAULT`: Unicode version 1.0.

- `UNICODE_2_0`: Unicode 2.0 and beyond (UTF-16 BMP only).
- `UNICODE_32`: Unicode 3.1 and beyond, using UTF-32.
- `VARIANT_SELECTOR`: From Adobe, not Apple. Not a normal
cmap. Specifies variations on a real cmap.
