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 many unique characters or symbols (the maximum number of characters that can be represented with one byte is [[256 (number)|256]] characters, while two bytes can represent up to [[65536 (number)|65,536]] characters). Examples of such languages include [[Japanese language|Japanese]] and [[Chinese language|Chinese]]. [[Hangul]] does not contain as many characters, but [[KS X 1001]] supports both Hangul and [[Hanja]], and uses two bytes per character.
