This is a proposal to add several Cyrillic characters to the international character encoding standard Unicode. These additions were published in Unicode Standard version 5.1 in March 2008. This proposal includes characters used for various communities, including a number of non-Slavic minority languages (Mordvin, Kurdish, Aleut, Chuvash, and Abkhaz). It also includes additions for early Slavic philology and linguistics and for ecclesiastical works.
