Wrong sorting of film rolls in collections when using accented characters

[elman22]

Describe the bug

Collections widget has wrong sorting when using accented characters. For example letter č should be correctly placed between c and d. So for example currently I have ordering:

• a, c, d, z, č, š

And correct ordering should be:

• a, c, č, d, š, z

Add to library folder picker has correct ordering.

Steps to reproduce

Just import folders with accented first letter and view collections.

Expected behavior

Sort folder in order defined by regional setting on computer.

I cannot reproduce on macOS:

Do you have the correct setting (sort film rolls by folder name) in the preferences of the collection module?
