by the way，readme also mention this

Thanks,bro. I just wanted to use this library to generate a subset of a font file, but later I found another library called Fontmin that can achieve the same functionality. In comparison, Fontmin has a smaller size and is easier to use. I hope this can help you.

Nice call on fontmin, it worked! I was getting font glyphs being set at undefined positions (not unicode points) in fontkit, but fontmin worked.
