[ft-devel] Question on Freetype/OpenType feature

[Funda Wang]

Hello,

Can freetype process TrueType/OpenType feature correctly?

Some glyphs should look different in zh_CN and zh_TW locale, so
CJKUnifont[1] have been using TrueType feature (glyph substitution)
to replace certain glyphs in specific language:

feature trad { # Traditional Forms
 script hani; # CJK Ideographic
 language ZHT  exclude_dflt; # Chinese Traditional
    sub uni9AA8 by uni9AA8_tw;
} trad;

feature smpl { # Simplified Forms
 script hani; # CJK Ideographic
 language ZHS  exclude_dflt; # Chinese Simplified
    sub uni9AA8 by u109AA8;
} smpl;

Can freetype deal with such feature correctly by mapping language to
system locale? Or, do you have any suggestions on such issue?

Thanks.
