One possible solution is the following: 1. Try to locate the unicodesymbols file (it's in the LyX's lib/resource directory, but I'm not sure where this is on Ubuntu). 2. Add a line line 0x0462 "\\textcyr{\\char176}" "textcyr" "" # CYRILLIC HISTORIC SMALL LETTER YAT to this file after the line: 0x045f "\\textcyr{\\char182}" "textcyr" "" # CYRILLIC SMALL LETTER DZHE 3. In LyX: Insert->Special Character->Symbols, Category=Cyrillic. At the end of the list of symbols shown, there will be a square. This is your Yat character. If you insert this character in your document it will be outputted correctly as the yat (although it will look like a square in LyX). Alternatively, you can enter in the command buffer: "unicode-insert 0462" and probably it will work too when using the Character Map. Does this work ? Vincent
