Bug#795674: steam: Can't type in russian

[Beta]

Package: steam
Version: 1.0.0.50-5
Severity: normal

Dear Maintainer,

Last update of steam package prevents me from typing in russian in chat and
forums. Deleting

# use C locale (bug #764311)
export LANG=C

lines from /usr/games/steam solves this problem.

~$ locale -a
C
C.UTF-8
en_US.utf8
POSIX
ru_RU.utf8
