fancyvrb.sty is not properly interacting with inputenc. i used this
patch to solve the problem:

 %% DG/SR modification begin - May. 18, 1998 (to avoid problems with ligatures)

it does not solve the problem in full, but it was sufficient for
e.g. making the russian translation of lshort work.

i can rewrite the patch to be 100% correct, but last time i was
interacting on this issue with the fancyvrb authors, they refused to
make changes to fancyvrb related to handling 8-bit characters.

i think it will be better to use the option "unicode" of hyperref,
then all characters are supposed to be translated to bookmarks
properly.

Best,
