In browser it's:

LANG=
 LC_CTYPE="C"
 LC_COLLATE="C"
 LC_TIME="C"
 LC_NUMERIC="C"
 LC_MONETARY="C"
 LC_MESSAGES="C"
 LC_ALL=
[download]

In console:

LANG=ru_RU.UTF-8
 LC_CTYPE="ru_RU.UTF-8"
 LC_COLLATE="ru_RU.UTF-8"
 LC_TIME="ru_RU.UTF-8"
 LC_NUMERIC="ru_RU.UTF-8"
 LC_MONETARY="ru_RU.UTF-8"
 LC_MESSAGES="ru_RU.UTF-8"
 LC_ALL=
[download]

Problem is solved here 1197669, although i don't understand why strings are different in console and CGI.
