But we are just one step away of having mule-charsets.el DTRT in Emacs
24 as well.  Is the effort of making it work with MULE-is13194.map is
so significant?  Can you tell me what needs to be done to support that
charset?  I'll then code that myself.  Who knows, we might need this
some day, even if that day is far away.
