Strange language in guild chat

Hello everyone!,
When I write in my guild chat, I see my lines correctly, but I see the other members to write in Arabic. I have some functionality wrong?
I put here a screenshot of the situation.
Thank you in advance.

They may have set their language to arabic... the game does not auto translate the text entered
