Windows-1251

Windows-1251 (also known as code page CP1251) is a popular 8-bit character code, designed to cover languages that use the Cyrillic alphabet.

Introduction

The original ASCII code was designed to work in 7 bits which offers 128 separate characters. The first 32 (0 - 31) were reserved for control codes but most of the rest are printable. The character 127 was defined to implement the backspace/delete functionality but on some devices it will be shown as a small box if coded. Since most items in a computer are stored in bytes with its 8 bits there are another 128 characters that could be used. The Windows-1251 code is designed to use these codes for the Cyrillic alphabet and is much more commonly used than the ISO 8859-5 standard intended for the same purpose but was never really adopted by these users. (It is missing some Ukrainian characters.) In the future, both may eventually give way to Unicode which is the preferred character set.

1251 Code page layout

The following table shows Windows-1251. Each character is shown with its decimal code and its Unicode equivalent.

Note that the word codes shown are for reference. They will not normally generate these values but will likely generate the equivalent ISO or UTF-8 values depending on the reader (see special characters). The full Windows-1251 includes ASCII values. The ones shown here are unique to this coding.
