In hopes of better defining the dilemma, some of the forth and on that
might otherwise be missed: the filesystem-comparison function, in addition
to the obvious business with mountpoints, must be an equivalence relation:
in particular, it must be transitive.  This worsens the aforementioned
issue of i, I, and İ for obvious reasons: the latter two must be
considered distinct in Turkish, but English considers the first two
identical-up-to-case and Turkish considers the first and last IUTC. 
Certainly each filesystem could have its own equivalence relation, but the
creation of a filesystem just to hold files whose names are in a different
language causes its own problems (such as defeating the rather reasonable
idea of hardlinking English and Turkish words to the same file to provide
simple bilingual support).
