The issue of extended character sets has been on the back-burner at the
RFC Editor for the past several years.  Yes, it "would be nice".
Unfortunately, it appears to us that this path is full of deep, deep
pits of non-interoperability!  There are no widely-available tools for
reading, searching, comparing, editing, or printing documents
containing UTF-8 and friends, as far as we know. (We would be happy to
be proven wrong.)
