UNIX Unicode APIs (*not* character sets)

[jarkko . hietaniemi]

Hi,

what is the status of various UNIXes and lookalikes as far
as "Unicode objects", that is, anything named using Unicode
encodings like UTF-8 or UTF-16XX, are concerned.
The most likely candidate for such naming of course
being filesystem objects, that is, filenames.  I know that Win32 has
something called "wide names" in NTFS. In UNIX lands NFSv4 (whenever it
comes out...Solaris 9?) is supposed to have UTF8 filenames.  But is there
anything else out there/being planned?
