Health, just because a language is written in a different alphabet does not make it different. Western European languages were written in Gothic script until about 350 years ago. German continued to use it until aout 100 years ago. Are they now different languages? What about Judeo-Arabic, etc. which everybody agrees are dialects?
You can hold that Yiddish is a different language but I can hold that it’s a jargon. Go mekadesh a woman on condition that it’s a language and then you can bring me a pesak.
