And I might now disagree with my past self.  While non-ut8 characters
are perfectly valid unix filenames, and I think everyones life is easier
if we generally stay out of the utf8 business it seems that for this
particular use case (shared filesystem with Windows, right) just
accepting utf8 should be fine.  ZFS is doing, MacOS X apparently is,
and NFSv4 requires it, although as far as I know most implementations
ignore that requirement.
