Northern Thai language name change

Tai Tham is in Unicode and I can see this text on my computer.

However, I have a few questions:

  1. Do you actually know this language? You translate to a lot of languages. It's better if native speakers do it.
  2. Till now, Northern Thai has been written here in the Thai script. How much is the Tai Tham script used?
  3. Is the name you propose written anywhere outside Wikipedia? For example, in books or academic articles?
