You see the difference? NA is releasing it to you globally but we speak English so we translate it into English characters because the majority are English native speakers playing it and the translator is probably an English speaker working in America who is publishing the game that was brought to them overseas, globally, in English because it's being published from America.
I don't care about translation on other languages, lol. Even if this game was translated in my language, I would play it in English. But why I can't type non-ASCII characters (well, font supports them, and Japanese version doesn't have this weird limitation). You can't write even English words like "café" and "naïve" btw.
