Maybe, the proposal sounded like this. I'm not an advocate of such
solution, which would only add complexity to the kernel without helping at
all the legacy applications which don't use UTF-8.

But I still think that the default for all applications should be UTF-8,
as prototyped by the GTK+ library, and so it should be the default for
Unicode-using filesystems like Joliet. (It seems that's what Jaromir just
did - thanks.)
