==> Caveats
This unicode-path version implements a hack to deal with composed/decomposed
unicode handling on Mac OS X which is different from linux and windows.
It is an implementation of solution 1 from
http://svn.collab.net/repos/svn/trunk/notes/unicode-composition-for-filenames
which _WILL_ break some setups. Please be sure you understand what you
are asking for when you install this version.
