standard> (UCs, IsO/IEC 10646) A 1993 IsO and IECstandard character set, also known as "Universal Multiple-Octet Coded Character set". UCs comes in a 16-bit variant called UCs-2 and a 32-bit variant called UCs-4, which is composed of 16-bit UCs-2 "planes". so far only one 16-bit plane has been defined, which is known as the Basic Multilingual Plane. The implementation of UCs isstill in its infancy, though some moves, such as the Java language defining a character to be 16 bits, are suggestive. [Relationship with Unicode?] (1997-07-04)
