Re: [fontforge-users] Combining Diacritical Marks

[Gé v. G. <gev...@gm...>]

OK, Michel, that was a good check. So I’ve looked around and got a new view
on the situation:
https://docs.microsoft.com/en-us/typography/opentype/spec/gpos#lookup-type-4-mark-to-base-attachment-positioning-subtable
This looks like the behavior doesn’t depend on the Unicode codepoint, but
on an OpenType table added to the font.

I guess BirdFont doesn’t let the user create or edit anchor points and thus
doesn’t generate those tables, so after all, it was the right thing to ask
on the Fontforge forum!
(If you want to make sure, that would be a specific question to ask the
BirdFont developers: "Does your program support creating/editing anchor
points?")
