See the description of the normalization and utf8only properties in the zfs(1) man page.
I think this might help you. normalization =none | formD | formKCf Indicates whether the file system should perform a unicode normalization of file names whenever two file names are compared, and which normalization algorithm should be used. File names are always stored unmodified, names are normalized as part of any comparison process. If this property is set to a legal value other than "none," and the "utf8only" property was left unspeci- fied, the "utf8only" property is automatically set to "on." The default value of the "normalization" property is "none." This property cannot be changed after the file system is created. utf8only =on | off Indicates whether the file system should reject file names that include characters that are not present in the UTF-8 character code set. If this property is expli- citly set to "off," the normalization property must either not be explicitly set or be set to "none." The default value for the "utf8only" property is "off." This property cannot be changed after the file system is created. -- Darren J Moffat _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
