Fix filter on filenames with diacritical marks

• [BUG] Can't filter on Å and å #19

Issue

Can't filter on file names with å and Å. In looking for a fix, I found it it's called characters with diacritical marks

Solution

I got some help from ChatGPT.
This solution normalizes words by splitting the diacritical marks in the filter function, so now forhånd and forhand result in the same files. Before, when trying to filter on forhåndsvisning, I had to stop after forha, because the filter didn't match anymore (in the filename, the å was split up in a and º, but I couldn't type that in the filter of course).
After it has normalized the characters, it then removes the diacritical marks. They're still displayed in the overview, but in the filter function, they are ignored.

Impact

I can't imagine this will have any impact on either the codebase, performance or backwards compatibility. It'll only impact users (positively!) who work with alphabets with diacritical characters

Usage Changes

Filter now supports filtering on words with diacritical characters

Considerations

I got help from ChatGPT to fix this. I think it's a good idea if a "real" developer takes a good look at the solution before merging it into the main branch.

Testing

No unit tests included, but I also doubt there has to be a unit test for such a small addition?
