Excuse me, what required is a tool converting an Unicode text to
a serie of glyph IDs for a given font, something like:

$ ./get-gids-of-font-by-unicode-str.exe test_font.ttf < sample.utf8
gid128
gid81
...

# There might be some discussion if the input like "U+xxxx" is better
# or raw Unicode text is better.

If the glyph IDs with no consideration of OpenType layout are sufficient,
it is not so difficult to make such tool with FreeType2. I will try.
Also it is not so difficult to make such tool by Perl if the dependency
to TTF module is acceptable.
