Can you confirm whether:
A) the contents of the minibuffer (or e.g. a dired buffer) are
   in decomposed format (i.e. can you backspace the accent marks
   separately with DEL)?
B) the filenames are returned in decomposed format, normal
   UTF-8, or some other format from readdir()?
C) Does installing the utf-8m encoding from Carbon Emacs solve
   the problem?
