The Russian alphabet has many systems of character encoding. KOI8-R was designed by the Soviet government and was intended to serve as the standard encoding. This encoding was and still is widely used in UNIX-like operating systems. Nevertheless, the spread of MS-DOS and OS/2 (IBM866), traditional Macintosh (ISO/IEC 8859-5) and Microsoft Windows (CP1251) created chaos and ended by establishing different encodings as de facto standards, with Windows-1251 becoming a de facto standard in Russian Internet and e-mail communication during the period of roughly 1995–2005.
