I have two fonts:
- font A: open-source font
- font B: proprietary font whose metrics I'm trying to match.
How do I create a replacement font (font C) with the glyphs from font A but with the metrics from font B?
Also, I want all characters not present in font B not to be present in font C and I want to receive a warning for every character present in font B but not in font A, so that I can create a replacement that supports the exact same characters.
I think that fonttools would be a good tool for this, but I am not very familiar with the way it works.
