Character sets and encodings

A character set is a standardized set of characters. It is often used to define which characters are supported by a particular format or software program. These characters include printable characters and control characters. Unicode is a character set with 149,186 characters. ASCII has a character set of 128 characters.

A character encoding is a mapping between a character set and binary values.
