League of Legends i can print only in English letters

I successfully installed Lol (AppImg w / d9vk). Everything works great, except that I can’t print anything in Russian. Neither in the launcher, nor in the game itself. In this case, I can paste the text in Russian from the clipboard. Russian is displayed correctly everywhere. In other games installed through Lutris, everything works well. For example, in osu! and overwatch.
How can this be solved?
I use Manjaro + KDE.
And yes, I’m sorry for my broken English.

Hello! I have the same problem on League of Legends with AppImage Wine
