        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.
