What is a character set name?
A coded character set is a mapping between a set of abstract characters and a set of integers. US-ASCII, ISO 8859-1, JIS X 0201, and Unicode are examples of coded character sets. Some standards have defined a character set to be simply a set of abstract characters without an associated assigned numbering.
What is the Unicode character set?
Unicode. Unicode is a universal character set, ie. a standard that defines, in one place, all the characters needed for writing the majority of living languages in use on computers. It aims to be, and to a large extent already is, a superset of all other character sets that have been encoded.
