Hmm, only two, AFAIK: Vietnamese has a set of tone marks (acute,
grave, hook, tilde, dot below) which can be applied to a base letter,
and some of the base letters have an accent (breve, circumflex, horn).

This isn't correct since Unicode contains all Vietnamese letters in
precomposed form. Anyway, this is an exception.
