It can be done in library level, or perhaps per process codeset
attribute in kernel. Thus don't have to change all userland.

MS-DOS filesystem long filename extension uses both Unicode and
Shift_JIS in same filesystem, I don't have enough clue about Joliet
extension, but I suppose Joliet is same with msdosfs. (to achieve
compatibility to existing Shift_JIS CD-ROM).
