Which ones do and which don’t?
It might help everyone to view the following map. Any country in green is Latin/Roman based

After that it's just a case of ticking them off, left to right
Morocco, Algeria, Tunisia, Libya, Egypt, and so on...….
e.g.
CN-RGU Royal Air Maroc (Arabic on the left, French on the right)
7T-VAL Air Algerie (dual presentation on both sides; however, the earlier scheme (1960's) featured Arabic written "first", whereas the later scheme shows French first.
But because arabic script is written in the reverse direction .....
A curious fact that is not strictly part of your question, is that airlines such as Thai International, whilst displaying purely English titles, would write the aircraft
name in Thai on one side, and English on the other.
Here is HS-TGO, "Srichulalak" - but if you go large with the photo you will see that on this side under the cockpit window it is written in Thai as "~~~~~~~~" (sorry, can't even get close with my keyboard)
Nothing to see here; move along please.
