Oracle Rdb supports multiple character sets and lets you use more
    than one character set in a database. The supported character
    sets are:

    o  ARABIC

    o  BIG5

    o  DEC_HANYU

    o  DEC_HANZI

    o  DEC_KANJI

    o  DEC_KOREAN

    o  DEC_MCS

    o  DEC_SICGCC

    o  DEVANAGARI

    o  DOS_LATIN1

    o  DOS_LATINUS

    o  HANYU

    o  HANZI

    o  HEX

    o  ISOLATIN1

    o  ISOLATIN9

    o  ISOLATINARABIC

    o  ISOLATINCYRILLIC

    o  ISOLATINGREEK

    o  ISOLATINHEBREW

    o  KANJI

    o  KATAKANA

    o  KOREAN

    o  SHIFT_JIS

    o  TACTIS

    o  WIN_ARABIC

    o  WIN_CYRILLIC

    o  WIN_GREEK

    o  WIN_HEBREW

    o  WIN_LATIN1

    The various ways characters can be coded are:

    o  Single-octet

       A single-octet character set is entirely represented in one
       octet. ASCII is an example of a single-octet character set.
       Each ASCII character is represented in one octet.

    o  Multi-octet

       A multi-octet character set is, in general, entirely
       represented in one or more octets. Some character sets are
       fixed multi-octet character sets and some are mixed multi-
       octet characters.

       -  Fixed multi-octet

          A fixed multi-octet character set is represented by two
          or more fixed number of octets. Kanji is an example of a
          fixed multi-octet character set. Each Kanji character is
          represented in two octets.

       -  Mixed multi-octet

          A mixed multi-octet character set is represented by one or
          more mixed number of octets that allow the use of ASCII and
          a fixed multi-octet character set in the same string. DEC_
          KANJI is an example of a mixed multi-octet character set.
          The ASCII characters are represented in one octet, and the
          Kanji characters are represented in two octets.
