Still a lot of websites (including Google) ignore "Accept-Language" header, and show language based on my geolocated IP address. Dude, if I'm visiting Netherlands it doesn't mean I speak Dutch. At least I can guess some words cause it's Latin alphabet. But when I visited Georgia I had no idea what მიღება even sounds like.
But despite having learned the Georgian alphabet and being able to read მიღება as "migheba" I still am none the wiser since I have no idea what that means.
Today my kid bought a pokemon toy and the box was only in Japanese. I proudly deciphered ニャスパー as "nyas'paa" but my son only recognized the name when I googled it and found the English spelling "nyasper" (we're not native English speakers so perhaps the translation would have been more obvious to some of you).
Long story short: knowing writing systems is super fun but often you need to know more about the actual language. That's especially true with languages like Arabic that don't spell out all the vowels
