When the parent of “a” kern are the all a alternate & multilingual (áâàäåã) will follow the kern automate?
If “áâàäåã” and “a” are all members of the same kerning class, they will share the same kerning values.
If you wish to define different kerning values for Tä or Tã etc., you need to make another kerning class containing those lowercase a with diacritics that might clash: à, ä, or ã.
i will try , thanks
