Cyrillic Alphabets Karel Piska Institute of Physics, Academy of Sciences 180 40 Prague, Czech Republic E-mail: piska@fzu.cz, piska@cern.ch WWW: http://www-hep.fzu.cz/~piska/ A collection of Cyrillic-based language alphabets is presented. The contribution contains the data about more than 50 languages using Cyrillic script. A "Unicode-like" coded font is used for the rendering of the Cyrillic texts. The aim is to take part in creating a universal Cyrillic font for TeX and the Omega project and to further help languages using Cyrillic join the TeX community.
