Hi,
To parse OpenType tables at low level and
obtain the substituted glyph index, libotf
might be useful.
http://www.m17n.org/libotf/
It does not provide the database of the
tags of script, language and features, and
no dependency/conflict checker of each
features. So libotf client programmer have
to read OpenType spec and choose appropriate
script/language/feature to apply to the serie
of the glyph index.
Regards,
mpsuzuki
