    And Kent responded, for which I must supply a few corrections:

    > 1) These characters were relatively recently encoded in Unicode,

    False. They date from the original publication of 10646-1:1993
    (and Unicode 1.1 as well, of course).

    > and there is likely not very many documents using the ornate
    > parentheses in a Unicode encoding.

    False. Although, of course, it is always possible to quibble
    here about what "not very many" actually means.

    > Furthermore, they are not
    > present in commonly used non-Unicode encodings.

    False. This is why HCI explicitly requested they not be
    mirrored. They *are* present in the Iranian national standard,
    deliberately synched with Unicode for Bidi.

    Of course. But see my other reply in the thread. This is *deep*
    history, and goes back way, way, way before the beta discussion
    for Unicode 5.0.

    I agree with that assessment for the quote marks, which is
    why I opposed changing their mirrored status all along.
    But it turns out that there are folks already heavily invested
    in the anomalous mirrored status of FD3E/FD3F as well. So
    it is basically hopeless trying to pursue any change for
    them further.
