1. this patch is for -stable. Some hunks would be failed for -current.
2. Only Page 00 Unicode is shown (for Joliet CDs).
ISO-8859-1 is OK, CJK is NG.
Each CJK character is replaced with '?' and file identity is lost
e.g. both 'abc' and 'xyz' are shown '???', and an access to '???' is
always directed for 'abc'.
( Note: 'abc', 'xyz' are CJK string,
ASCII string has no such problems. )
I think it would be solved
if kernel had NLS and multibyte functions(or their subsets).
( Linux 2.2.x has in-kernel-NLS and Linux's Joliet feature
uses it; however, there are no official CJK supoprts.)
Note.
Byung's patch passes Unicode transparently.
So CJK filenames are shown if terminals do Unicodes well.

Would you tell me what kind of problem?
Known bugs of Byung's (Already fixed):
* Shortname is also shown not only longname on some Joliet CD-Rs.
* Joliet support is not work with El Torito CD-ROMs.
Changes from Joachim's:
* With Joliet and RockRidge CD, Joachim's see Joliet, mine see RockRidge.

-j is also available for my patch.
