A double-byte character set (DBCS) is a character encoding in which either all characters (including control characters) are encoded in two bytes, or merely every graphic character not representable by an accompanying single-byte character set ( SBCS) is encoded in two bytes ( Han characters would generally comprise most of these two-byte characters). A DBCS supports national languages that contain a large number of unique characters or symbols (the maximum number of characters that can be represented with one byte is 256 characters, while two bytes can represent up to 65,536 characters). Examples of such languages include Japanese and Chinese. Korean Hangul does not contain as many characters, but KS X 1001 supports both Hangul and Hanja, and uses two bytes per character.
A DBCS, Double Byte Character Set, is an encoding in which characters are encoded in two bytes.
