There are only so many possible file format names. I once had a file whose format(creator, iirc) was the same as The Sims House Party, so the document was listed as "The Sims House Party Document" even though it wasn't.
I assume that Növa is used because in addition to sticking with the umlauts over a letter, there's probably a program out there that uses the Creator 'Nova' or something.
The same is true with resources in ResEdit. EV uses specific resources, so it wouldn't be good to have the names conflict. of course, it would be obvious if you made a resource name that conflicted with one existing, but having them be unique is... ...better.
