The way I'm reading that man page, it seems like with ZFS you have one option to choose whether to use normalization: 'nomalization = "none|FormD|FormKCf"' And a separate option to choose whether to accept non-utf8 filenames: 'utf8only = "on|off". The default setting appears to be that ZFS does allow non-utf8 filenames. Whereas with Olaf's series you have one option that turns normalization on or off, and he is not giving you a choice of whether non-utf8 filenames will be accepted (they will be accepted). So IIUC there is a distinction: The utf8 support for ZFS is "more optional" than the utf8 support for XFS.
