Adds information. Within the DESCRIPTION clause, this is
    information documenting the partition; within the AUDIT clause,
    it is a history list entry. Valid delimiters are /* */ or double
    quotation marks (" ").

    You can use Japanese to document comments in the DESCRIPTION or
    AUDIT clause for a field. To do this, use the SET CHARACTER_SET
    command, and set the character_set of the session to DEC_KANJI.
