Hi support people.
What I'm trying to do is make some new letters in open type font by combining existing glyphs, actually, copy-pasting them, so that I would get - for example letter č by pasting c and putting caron on in, but I get this error, warning that is:
Current font contains original OpenType tables. If you continue with the operation data will be removed.
It asks me - Do you want to continue? I say yes, but when I export made font, system doesn't recognize letter. So, please tell me
how to do this properly?
