The umlauted u is not just a u with some visual flair. "ue" instead would be a more accurate transliteration, but Tuerkiye looks... awkward.

Got it, but I’m saying that using “Turkiye” is better than using “Turkey”.

They are completely different letters. You'd be misspelling it.

Context matters. Is it better to use Turkey then?

Things like text search and exact string matching.

As minor as it might sound, if 199/200 countries work in your system, capitalism dictates that below a certain business size, the logical thing is often to just ignore the one country and move on.

These things have odd cascading effects.

I have good news for you - text search for non-ascii version of latin characters like ü is a long solved problem. That's because even in non-english speaking countries some people don't bother with diacritics, or they don't have a correct layout at that point, or the text is in source code and has to be ASCII, etc.

You can try that now - my browser highlights Türkiye when I search for Turkiye.

Great! Now do a JOIN in a database with Türkiye in one column and Turkiye in another.

It's a problem with well-known solutions. That's not the same as a solved problem.

It will be a solved problem when processing a log file in /var/log with Python (or any other tool of choice), it works automatically.

Because it’s hilarious to try to force the english speaking world to pronounce a name with letters they don’t have.
