Recently, I looked into Paltalk Unicode, I noticed that they have UNICODE support, but I am not able to enter Unicode text through paltalk window.
So I did some research and yet I was able to create an add-on to send Unicode text to Paltalk windows.

I called it UniTalker, it can sends Vietnamese, Chinese, Japanese, Koreans or any language that supports Unicode to Paltalk chatroom. This works well weither in the room or PM messages.
