There are such new ISO standards where all characters in the
8 bit set are defined (almost, I think there are 2 left positions
in there). The scheme is that the lowest 128 positions are equivalent to
ISO 646 international reference version and the upper part corre-
sponding to the *letters* in the lower part, are also letters. And there
is a correspondance between these letters in lower case and in upper
case like in the 7-bit part. You can exchange positions in the 7-bit
part with positions in the 8-bit part so for instance you can have an AE
in the right place (according to the Danish Standard DS 2089). Thus you
have backwards compatibility with ISO 646. I cannot give you the ISO
numbers right now, but I have them somewhere. There is both a Western
European version and an Eastern European version.

But as Kim says, this has nothing to do with the troff special char
discussion I raised. It can of cause be combined at some stage,
but not at the immediate level. Troff is still 7-bit, like the rest of
the world.
