Many languages have few enough characters to be represented in a single-byte character set. In such a character set, each character is represented by a single byte: a two-digit hexadecimal number.
At most, 256 characters can be represented in a single byte. No single-byte character set can hold all the characters used internationally, including accented characters. This problem was addressed by the development of a set of code pages, each of which describes a set of characters appropriate for one or more national languages. For example, code page 1253 contains the Greek character set, and code page 1252 contains Western European languages. There are many code pages, and many names for code pages. The above examples are code pages for Windows.
