This is just a thought experiment at the moment, but to what extent would we expect YAFFS to work with UTF-8 filenames? From what I have looked at of the guts, YAFFS is simply treating filenames as NUL-terminated octet strings, so it smells like it all ought to Just Work provided the given filenames are valid UTF-8 sequences?
