"Why Trados does not support Karen? "

I'm using Trados Studio 2019. But, it's not very useful to me as I can't do anything about Karen. It seems to me like a gun without bullets. :) 

I just can use it for Burmese translation. Karen is one of the ethnic groups in Myanmar. We primarily use KNU font for translation. 

It will be a great help to me if I can use Karen in Trados.
