xkcd-Script: GSUB/GPOS problem

[dummy-index]

Hello.

Latest auto-generated font files maybe have lost one's kerning & ligature information. (Initially I thought that GSUB/GPOS tables in .sfd aren't displayed for some reason, ...) Maybe it is caused by the method generating the .sfd file. https://github.com/dummy-index/xkcd-font/commits/brushup

I am up to refine xkcd-script (ascend (inconsistent with em), charmap (small letter x and cross product, ...), letter spacing w/o kerning, ...) I don't know about docker, I use python and ffpython.exe jointly. Far from pullreq.

2020/10/25 I found that this xkcd-script.sfd is in PFB format in reality! font.generate() doesn't recognize .sfd extension. We shuld use font.save() instead.
