    Note that plane 15 occurs in the kIRG_TSource. The official IRG
    sources on occasion differ from their printed counterparts, typically
    to allow inclusion in Unicode of characters which have not yet been
    officially standardized in their home country.

    What "plane 15" means in this case is that the Taipei Computer
    Association, which owns CNS 11643, handed the IRG a set of mappings
    which contained this mysterious plane. That's as much an answer as
    you can get from the Unicode end of things. For more information,
    you'll have to contact TCA.

    Note that the kCNS1992 field does *not* contain plane 15 mappings.
