Oh wow, that’s terrible. My spellchecker needs to be updated because it doesn’t want me writing “Turkiye.”
"Turkey" is the correct spelling in English. The Turkish government doesn't get to dictate what their country is called in other languages.
Some people in the government renamed the english spelling of my city into an unreadable alphabet soup. Not only they strongly insist the whole world to spell it this way, they also deem everyone who doesn't like it a traitor.
So, spelling matters. A lot. Unfortunately.
