BUG FOUND!!!
when entering phonemes with “.”, some characters are replaced.
I put the phonemes: .i` .iº .iª .ts`h .i´ .a¨a
and instead got i' io ia ts'h .i´ .a¨a (with hidden space+combining diacritic you can’t see)
While most of these are non-ASCII and will therefore likely never be added into actual phoneme support for any language, one of these, the grave a.k.a. backtick, would “fudge up” Chinese support which relies on this character.
