Dear Guenter, Thank you very much for your suggestions! It seems that XeTeX is indeed a feasible way to print some old-orthography Russian letters. And this is great! However, a more ambitious task, which is similar to enabling Greek polytonic, would be to enable the true Church Slavonic in LyX, which would be amazingly useful. Church Slavonic looks quite different to ordinary Russian (a sample of Church Slavonic can bee seen on Wikipedia, at http://en.wikipedia.org/wiki/File:Csl-luke20.png), and is rich in diacritics, so it requires its own fonts, such as Irmologion or Triodion (can be seen here - http://www.irmologion.ru/fonts.html). I am not sure Church Slavonic characters are included in Unicode. What I know, however, is that attempts have been made to create TeX packages that make it possible to typeset in Church Slavonic - one such package is HipTeX (http://www.sobor.org/hip/); another (and supposedly better one, since it is more recent and avoids certain drawbacks of HipTeX) is CSLTeX (http://sites.google.com/site/csltex/). They can be downloaded by clicking the zip files, but, unfortunately, documentation to both of them is in Russian. Can these developments be somehow incorporated in LyX? Andrey
