Please note that not all of these marks are just "marks" on some "normal" character, that you can remove without changing the meaning.

In Swedish, å ä and ö are true and proper first-class characters, not some "variant" of some other character. They sound different from all other characters, they sort different, and they make words change meaning ("mätt" and "matt" are two different words).
