Description of problem:
Russian man pages in the 8bit locale does not readable.

man-1.5k-6
groff-1.18.1-20

How reproducible:
Runs konsole in ru_RU.KOI8-R locale
(in KDE LANG=ru_RU.KOI8-R konsole &
and export LANG=ru_RU.KOI8-R in new konsole)
Then type:
man zic
and I can not look any russian characters!

I investigate the groff and found some stupid(?) patch for troff prog
called groff-1.18.1-8bit.patch.

Without that patch and with shanges in nroff like this (lines begins from symbol
'>' are changed):
...
CONV=
case "${LC_ALL-${LC_CTYPE-${LANG}}}" in
>  ru_* )
>    T=-Tnippon
>    echo ${LC_ALL-${LC_CTYPE-${LANG}}} | grep -q -v UTF-8$ && CONV="`locale
charmap 2>/dev/null`"
        ;;
  ja_JP.ujis | ja_JP.eucJP | ko_KR.eucKR | *.UTF-8)
    ;;
  *)
    CONV="`locale charmap 2>/dev/null`" ;;
esac
...

After this changes the man outputs correctly, except the length of charasters
It will be 1, but in this case it equal 2. And in 8bit locale symbol 'P'
printing as 'P ' for example.
