Adding ability to translate on messages and in chat

I sense that some users don't respond to messages or reply with one-word answers due to insufficient language knowledge. I've seen some mobile strategies integrate Google Translate, allowing users to write messages in their language, and others can click a button to get a translation. Moreover, I've personally integrated this feature into a game with 30k online players. It significantly increases engagement in communication (which is crucial in 1914, as diplomacy enhances the experience) and improves retention due to this increased involvement.
