I confirm there is a bug, you just have to adjust the test case:
$ echo Пример |iconv -tutf8 |LANG=ru_RU.utf8 grep -q "$(echo "[Пп]ример" |iconv 
-tutf8)"; echo $?
0
$ echo Пример |iconv -tkoi8r |LANG=ru_RU.koi8r grep -q "$(echo "[Пп]ример" 
|iconv -tkoi8r)"; echo $?
1
$ echo Sример |iconv -tkoi8r |LANG=ru_RU.koi8r grep -q "$(echo "[Ss]ример" 
|iconv -tkoi8r)"; echo $?
0
