I've also looked at it recently but my idea was to update kiconv to
handle ucs-2 (or whatever it is) -> utf-8 conversion in kernel. kiconv
supports different translation methods. Current implementation just
creates a table for ucs2->utf-8 conversion and passes it too kernel. It
seems it can't even handle all of unicode chars.
Fixing kiconv would be a better solution, imho.
