I cannot type any letter which uses '~' symbol. When I write English letters without using Baraha, I can type the '~' symbol, but I cannot type it in Baraha. Can you help me?
According to the developer, the '~' symbol will translate into the same symbol in other language. You should be able to use it normally. Also, I suggest that you visit the official support website. You will find there a few basic rules on how to write using the Phonetic Keyboard.
