Thank you for the reply, Werner!
I have found all the files: koi8-r.tmac, ru.tmac and
hyphen.ru (in the koi8-r encoding). The koi8-r.tmac file
consists of lines like:
.trin \[char186]\[u2568]
and I believe it maps UTF-8 to KOI8-R, hence I cocluded the
input file should be in the UTF-8 encoding. But alas! it
didn't work, reporting errors like this:
can't find special character `u2568'
But these characters are mentioned in the koi8-r.tmac file,
so I don't understand what happens...

PS: I have made sure that the koi8-r mapping file is used by
renaming it and calling nroff with -mru.
