<character, standard> (UCS, ISO/IEC 10646) A 1993 ISO and
IEC standard 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 is still in its infancy, though some
moves, such as the Java language defining a character to be
16 bits, are suggestive.

UTF-1
UTF-1 is a method of transforming ISO/IEC 10646/Unicode into a stream of bytes. Its design does not provide self-synchronization, which makes searching for substrings and error recovery difficult. It reuses the ASCII printing characters for multi-byte encodings, making it unsuited for some uses (for instance Unix filenames cannot contain the byte value used for forward slash). UTF-1 is also slow to encode or decode due to its use of division and multiplication by a number which is not a power of 2. Due to these issues, it did not gain acceptance and was quickly replaced by UTF-8.
