    That isn't true. They both define the same character set. (I will not
    use the term "charset".)

    The code position assignments are (formally) assigned by WG2, but
    there is consensus between UTC and WG2 on this matter.

    To me, "Unicode" refers to the most recent version. :-)

    Yes, I can.

    That isn't true. If you think this is true, you really have a lot to
    learn about Unicode.

    I think you mistook me.
