The iso9660 standard is 8.3.  There are several alternate extensions to
it:  Rock Ridge, and Joliet.  Both allow > 8.3.  Joliet was designed by
Microsoft to mainly address the 8.3 limit.  Rock Ridge added more Posix
semantics, including a lot of *nix-isms.  El Torito is bootable.  There's
also an Apple iso9660--presumably it handles dual-fork resources, although
I'm speculating there--I've never used it or read up on it.

No idea what format -that- is.  RR is up to 255 characters, Joliet is up to
64 Unicode characters.  I don't know of any between 8.3 and those.  Sounds
like a kludge.
