 114  DBCS (Short for Double-Byte Character Set), a character set that uses two-byte (16-bit) characters. Some languages, such as Chinese, Japanese and Korean (CJK), have writing schemes with many different characters that cannot be represented with single-byte codes such as ASCII and EBCDIC.
 115
 116  In CJK world, CES (Character Encoding Scheme) and CCS (Coded Character Set) are actually different concept(one CES may contain multiple CCS).
 117  For example, EUC-JP is a CES which includes CCS of ASCII and JIS X 0208 (optionally JIS X 0201 Kana and JIS X 0212).
 118
 119  In Japanese (because I am Japanese),
 120  While EUC-JP and UTF-8 Map ASCII unchanged, ShiftJIS not (However ShiftJIS is de facto standard in Japan). For example, {0x95, 0x5c} represents one character. in ASCII, second byte(0x5c) is back slash character.
