    Of course. I am only saying that there are no strong grounds within
    Unicode for the UTC to reject such new characters.

    I never suggested that it did. I hope it doesn't.

    Which is a very good reason for making it possible for the Chinese
    simply to add the extra characters they require to their existing
    standard, in a way which does not compromise the Unicode stability
    policy. Then they don't need a new standard which would complicate
    things for everyone.
