Re: [ft] TT_PLATFORM_MACINTOSH : which mapping converts Unicode into the expected encoding?

[Tom Sanham]

Thanks for the response.

I asked because I came across a very old font which contains no Unicode
mapping, and no glyph names; hence I wish to write a routine to
translate Unicode values into the legacy encoding supported by the font.

However I think I have now found the answer I needed:

The relationships between the legacy encodings and Unicode are specified
by the following document:

ftp://ftp.unicode.org/Public/MAPPINGS/VENDORS/APPLE/README.TXT

Thanks again

Tom

Hi,

Excuse me, FreeType2 has no feature to convert character encoding.
If you mean "how to select the charcode-to-glyph mapping table
for Unicode", the solution would be TT_PLATFORM_APPLE_UNICODE.
TT_PLATFORM_MACINTOSH is used for the legacy system before Unicode,
the recent Macintosh uses TT_PLATFORM_APPLE_UNICODE.
