Single-byte character

Extracted from the Wikipedia article Single-byte character set.
Single-byte character sets are contrasted against double-byte and triple-byte character sets as well as multi-byte character sets. Multi-byte character sets are used to accommodate languages with scripts that have large numbers of characters and symbols, predominantly Asian languages such as Chinese, Japanese, and Korean (sometimes referred to as "CJK"). In these character encodings, SBCS are traditionally associated with half-width characters, so-called because such single-byte characters would traditionally occupy half the width of a double-byte character on a computer terminal screen which used a duospaced font.
