Code page 866 (Cyrillic)

American Standard Code for Information Interchange (ASCII) is a widely used character encoding system introduced in 1963.

The original character set, which is now referred as the standard character set was initially composed of 128 characters (7-bit code). The first 32 characters are control characters (also called non-printable characters), which are used to control data streams as well as devices such as printers. It later was expanded to support 256 characters (8-bit code) in order to provide language specific characters, various symbols, as well as box-drawing characters: elements used for presentation purposes, allowing to draw different kind of frames and boxes. The characters in the 128-255 range are referred to as extended ASCII.

Code page 866 is the most widely used code page to write Cyrillic-based languages: Belarusian, Bosnian, Bulgarian, Macedonian, Russian, Serbian, Ukrainian (Slavic languages), and Kazakh, Kyrgyz, Moldovan, Mongolian, Tajik, Uzbek (non-Slavic), Code page 855 being the alternative one. Only the extended character set differs from the original code page, both the control characters and the standard character set being plain ASCII.

The character table below is showing a pixel precise graphical represention for each character, alongside with a text description.
