KOI8-T is an 8-bit single-byte extended ASCII character encoding adapting KOI8 to cover the Tajik Cyrillic alphabet. It was introduced by Michael Davis as an interim solution for representing Tajiki Cyrillic text in an interchangeable manner appropriate for use on the web, in an attempt to bridge the gap between existing non-interoperable font-specific encodings and the eventual wide adoption of Unicode. It is used by the GNU C Library as its default encoding for Tajik.
