    There is no earthly reason to consider this disunification.

    There are no hard and fast rules that will solve all future
    disunification problems. Believe me; I am king of disunifications. :-)

    The ordinary letters A-F are already used for this purpose with no problem.

    We did. We identified these as duplicate characters, that is, as
    characters already encoded.
