That's the wrong way of looking at an å.

It's not just an a with decoration. It actually has different pronunciation and is typically replaced with aa if no å is available. (I'm neither Swedish nor Norwegian, so not 100% sure, but it's what happened to Erling Haaland).

Similarly, you would replace a German ä with ae. So if my name was Bäcker, it would be wrong to spell it Backer on a ticket. Baecker would be the way.
