ISO 8859-5

Sponsorship the way you would do it

ISO 8859-5, also known as Cyrillic is an 8-bit character encoding, part of the ISO 8859 standard. It was designed originally to cover languages using a Cyrillic alphabet such as Russian, Ukrainian, or Belarusian, but never got widespread use.

The 8-bit encodings KOI8-R and KOI8-U, and also Windows-1251 are more commonly used. In recent times all of these may eventually give way to Unicode.
