    I have a question for an IBM character-set guru, concerning the mapping
    of Katakana characters to GCGID values, and specifically why they were
    mapped to the halfwidth compatibility characters at U+FFxx while
    Hiragana was mapped to the "real" characters at U+30xx.

    The reason I care is that I'm trying to take the large collection of
    code page mappings at, which are
    expressed in GCGIDs, and map them to Unicode code points instead.
