If you choose to spawn VERY far away from civilization you will have your own launguage and when you meet someone else you will have to try to communicate Quotes from Q and A:

"Q: If I were to start far away and meet someone, you mentioned that we would have to learn to understand each other, How would that work? Would chat be scrambled at first in some way even if both players spoke english?

A:Yes, it would be scrambled. It would take a long time for 2 characters to learn how to communicate with each other, but they will be able to teach each other starting immediately."
