  I agree, and I think they should be expressed in terms of context-free
grammar, for example for Turkish

  V -> a | â | e | ı | i | î | o | ö | u | ü | û
  C -> b | c | ç | d | y | g | ğ | h | j | k | l | m | n | p | r | s | ş | t | v | y | z
  S -> 2V1 | 1C1 | 2CC

  There is a Python library that can interpret that syntax directly.
I’ve already written a small script for Turkish in one of our
“lost” repositories.
