Have you ever tried to write in another language and getting weird symbols instead of letters? I have experienced that,
I mentioned that game cannot recongize ukrainian-specific letters when they are typed in chat, such as [Її, Єє, Іі] (however, when these letters are typed from latin alphabet (except Єє), everything is alright), but when [Її, Єє, Іі] is typed from ukrainian keyboard, game shows these letters as "=" [equal symbol], which makes ukrainian players suffer little bit.
I wonder if someone from dev team has ever wondered about such problems as chat encoding.
