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.
These things should never come down to the individual skill of the programmer. There should be systems and checks in place to assure the quality. And if the quality isn’t reached, the programmer needs enough time and support to reach them.
But we all know, being thorough doesn’t pay.
