You might have half a point about emojis, but that's not what Apple is doing here.

Is there a reason I as a Swede should be limited from using my full native alphabet in my passwords for example?

As an example, you know how people sometimes suggest using a short sentence as a password? Here's a phrase in a local dialect, which means "and in the river there's an island" Å i åa e ä ö

Notice how only 2 of those letters are available in ASCII.

ASCII only is not a feature, and I honestly doubt anyone would try to argue that it is if this was about any company other than Apple. Try to look past the "who" and focus on the "what".
