I don't think we are talking about the same problem. We are not
talking about the same (or similar) glyphs, we are talking about the
same characters: one character with the same encoding. UTF-8 allows
the same character to be encoded with different code! These charactes
have to have the same meaning (that's why OSX converts them to a
canonical form). The mentioned characters does not have the same
meaning (greek alpha vs. A and 0 vs O).

What I suggest is having a config option to at least allow OSX users
to use SVN with its full glory (I mean accented filenames). this
requires some kind of stringprep.
