It depends what exactly you do in TikZ. Especially when typesetting
along a curved path TikZ can insert some code between codepoints and
then the shaping engine does not see the correct groups of characters.
It might help to enclose a consonant with its vowel into braces so
that TikZ considers it one token and does not insert anything in
between.
