Specifies the valid characters that you can use for an element
    name, the initial value field property, and in comments. You
    must set the character-set parameter to DEC_KANJI when you use
    Japanese with Oracle CDD/Repository.

    If you omit the SET CHARACTER SET command, Oracle CDD/Repository
    references the equivalence name of the CDD$CHARACTER_SET logical
    as the character set for the session. If this logical is not
    assigned, the default character set is DEC_MCS.

                               RESTRICTION

       DEC_KANJI is not available through the CDO editor.

    Oracle CDD/Repository accepts a maximum field and record name
    length of 31 octets (31 characters for ASCII/MCS characters; 15
    characters for Kanji and Narrow Katakana).

    Oracle CDD/Repository accepts the following characters as the
    field and record name when the character-set parameter is DEC_
    KANJI:

    o  Kanji (Japanese characters as defined by the JIS X0208:1990
       standard)

    o  Katakana (Japanese phonetic alphabet, Narrow Katakana, as
       defined by the JIS X0201:1976 standard)

    o  ASCII characters (A-Z, a-z, _, $)
