I want use fonttools to Parse four bytes character font file, should I use it as from fontTools.ttLib import TTFont as f , or from fontTools.ttLib import TTFont as t1 , or others? Then should I use font = t1(font_name) or some other commands?

By four-byte you mean full Unicode range?

Yes, fontTools.ttLib import TTFont sounds about right. Or is it a Type1 font? Your description is very confusing.

The problem comes from the software. Thank you for your answer.
