As long as the iso10646 font is a font with the appropriate 
language-specifc variants, there should be no user-visible
difference, right?

But yes, certainly users will have native-encoded fonts, so we
should use them for things like jisx0212 as well as the encodings
we handle currently.

What I meant by "I don't seem to have that patch around any more",
is that I probably deleted it from my hard disk at some point.

I'll either try to redo this or to write up some more detailed
instructions for how to additional charsets.
