Cyrillic font with enUS, help needed

Hello, me playing on Outland 2.4.3, using enUS client as I mentioned. If I may ask, what else should I do, if I wanna communicate with my fellow russian teammates, using cyrillic font? I installed RU lang. pack in Windows. Then when I switch my language to RU(shift+alt), I am able to type cyrillic, but only in windows. When Im trying that ingame, all i see in chat is “???”, same seen by other players. Messages sent by friends I see normal, but they cannot see mine cyrillic. Is it possible to be seen with enUs client, or I just missed something? Thanks for help guys.
