@ABG The Following could work with the translator component however I also am not sure if it will pick up the ISO 639 - 3 abbreviation of the tmr (Jewish babylonian aramaic) as it usually uses the ISO 639 - 2 abbreviation. the language doesn't have a ISO - 693 - 2 abbreviation so not sure if it will work.
Much as I like to keep working hardware as long as possible,
I have no 2,000 year old keyboards in stock to test such translations.
The spaces around the '-' in the language code might be problematic.
Best I can do is refer you to the component help:
