Displays the character set of the current CDO session.

    You must set the character-set parameter to DEC_KANJI to use
    Japanese characters with Oracle CDD/Repository. Use the SET
    CHARACTER_SET command to specify the character set for a CDO
    session.

    If the setting has not been specified using the SET CHARACTER_SET
    command, Oracle CDD/Repository references the equivalence name of
    the CDD$CHARACTER_SET logical name. If this logical name is not
    assigned, the default character set is DEC_MCS.
