TT_PLATFORMS

A list of valid values for the ‘platform_id’ identifier code in FT_CharMapRec and FT_SfntName structures.

TT_PLATFORM_APPLE_UNICODE

Used by Apple to indicate a Unicode character map and/or name entry. See TT_APPLE_ID_XXX for corresponding ‘encoding_id’ values. Note that name entries in this format are coded as big-endian UCS-2 character codes only.

TT_PLATFORM_MACINTOSH

Used by Apple to indicate a MacOS-specific charmap and/or name entry. See TT_MAC_ID_XXX 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).

TT_PLATFORM_ISO

This value was used to specify ISO/IEC 10646 charmaps. It is however now deprecated. See TT_ISO_ID_XXX for a list of corresponding ‘encoding_id’ values.

TT_PLATFORM_MICROSOFT

Used by Microsoft to indicate Windows-specific charmaps. See TT_MS_ID_XXX 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).

TT_PLATFORM_CUSTOM

Used to indicate application-specific charmaps.

TT_PLATFORM_ADOBE

This value isn’t part of any font format specification, but is used by FreeType to report Adobe-specific charmaps in an FT_CharMapRec structure. See TT_ADOBE_ID_XXX.
