Well, that's invalid too.

I was using your patch (in a non-vanilla 21.2).  It looks as though
some of the insufficiently-tested changes I made for Emacs 22 were
responsible for the differences, sorry.  I think that just indicates
in another way that rfc2047.el doesn't DTRT.  I guess the use of Emacs
charsets saves it from going badly wrong in this case by chance, but
it's not generally right.  It's coding systems which are
(more-or-less) equivalent to MIME charsets and need to be checked, not
Emacs charsets.
