Why does TV Tropes always convert non-basic Latin characters into entities?

Why in the whole wide world does TV Tropes always convert non-basic Latin characters into entities? How can a Wiki website about pop culture handle these characters so badly? Fantasy, manga, anime, non-English works, etc. of course use a lot of foreign and strange characters, so the fact that a website dedicated to cover these topics can't simply handle text well in the text editor is bafflingly atrocious. Every time I save an article with non-basic Latin characters and come back, I'm way less inclined to fix errors now that everything has become an incoherent jumbled mess. Not to mention this always ruins any external links with non-basic Latin characters in them. I'm not gonna even say that TV Tropes' wiki-style text is unintuitive, it's straight up abhorrently bad. Whoever coded this website or its text engine, please take a clue from Wikipedia or Fandom.

Those are bugs. They're on the long list of things to be fixed when the developers have time. It's not a personal assault on non-English people; chill out.
