So, I've just exposed my ignorance on this issue.  I haven't really had
to think about filename character (en)coding before.  (I'm another one
of those mono-lingual Americans...)  Last time I played in the guts of
a filesystem was when I was hacking CP/M systems.

From what I've been able to read so far, it may be an issue with how
the UTF-8 character is being normalized to the UTF-16 underlying HFS+.
Apple uses NFD while almost everyone else uses NFC.  Again, I don't see
why this might cause a problem, as I thought it should be a transparent
issue for the filesystem layer.

Whatever is at issue, it keeps me from un-tar-ing files with filenames
containing characters 0x80-0xff on HFS+ (whether case-sensitive or not).
