Xerox Character Code Standard
Obsolete character code standard developed by Xerox Corporation

The Xerox Character Code Standard (XCCS) is a historical 16-bit character encoding that was created by Xerox in 1980 for the exchange of information between elements of the Xerox Network Systems Architecture. It encodes the characters required for languages using the Latin, Arabic, Hebrew, Greek and Cyrillic scripts, the Chinese, Japanese and Korean writing systems, and technical symbols.

It can be viewed as an early precursor of, and inspiration for, the Unicode Standard.

The International Character Set (ICS) is compatible with XCCS.

The XCCS 2.0 (1990) revision covers Latin, Arabic, Hebrew, Gothic, Armenian, Runic, Georgian, Greek, Cyrillic, Hiragana, Katakana, Bopomofo scripts, technical, and mathematical symbols.

Retrieved 2016-10-25. In 1978, the initial proposal for a set of "Universal Signs" was made by Bob Belleville at Xerox PARC. Many persons contributed ideas to the development of a new encoding design. Beginning in 1980, these efforts evolved into the Xerox Character Code Standard (XCCS) by the present author, a multilingual encoding which has been maintained by Xerox as an internal corporate standard since 1982, through the efforts of Ed Smura, Ron Pellar, and others.Unicode arose as the result of eight years of working experience with XCCS. Its fundamental differences from XCCS were proposed by Peter Fenwick and Dave Opstad (pure 16-bit codes), and by Lee Collins (ideographic character unification). Unicode retains the many features of XCCS whose utility have been proved over the years in an international line of communication multilingual system products. /wiki/Joseph_D._Becker
