Code Pages in Windows

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.

A maximum of 256 characters can be represented in a single byte. No single-byte character set can hold all of the characters used internationally, including accented characters. This problem is addressed through the use of code pages, each of which describes a set of characters appropriate for one or more national languages. For example, code page 869 contains the Greek character set, and code page 850 contains an international character set suitable for representing many characters in a variety of languages.
