Indeed, that looks like the culprit (IIUC it's not done by the
filesystem, but by the OS itself before it passes the file names to the
filesystem, so it applies to all filesystems).

Rather than "perhaps", it should say "supposedly".   Please try out this
new ucs-normalize package and tell us if it solves your problem and/or
suffers from other problems.  It likely won't make it for Emacs-23.1 but
should be included in Emacs-23.2.
