Unfortunately, that may break some existing installations which have
multiple codesets as pathnames in a single FFS.
You can say such filesystem is broken (and I may agree ;-)), but
I think it isn't an option to break existing installations.

Apparently, we need a converter which converts all codesets to
unicode (and vice verse) in our kernel (for NFSv4, NTFS, VFAT,
etc...), but using single codeset as an intermediate codeset like
above cannot solve the problem.

But an extended iconv-like interface can...
