Actually, I think this is not such a good idea for Unicode, which was designed
precisely to AVOID such things. If you need to support ISO-2022, perhaps you
could just support it; and then invoke Unicode within it if you need to? It
think there is an ISO-2022 invocation sequence for Unicode...some standards
guru may know.

And the CNS issue is something that the CJK IRG is working on, certainly, and
eventually there will (likely) be a solution that satisfies the community
which needs the said CNS characters. I wouldn't look upon this as a permanent
disability of Unicode. If you have specific character requirements, you could
forward those. I'm under the impression that Unicode's CNS coverage is already
adequate for all but the most obscure situations.
