Funfact: iOS does support setting Klingon as a preferred language 😉

@eurasierboy disappointing fact: It doesn't support a significant number of naturally-occurring minority languages spoken by different people around the world.

Like any Sami language except Northern.

@piecritic is there even a reason iOS doesn't support the entire ISO 639-3 I should know or is that just a setup for more disappointment
@piecritic like I understand how difficult that would be for system languages, but allowing the setting for preferred if an app supports it seems like a no brainer? 😕
@eurasierboy it's just to disappoint you. It's ridiculous. At least Windows 10 lets you globally extend the locales list with cldr data.
