Sorting order has changed recently for non alphanumeric characters

Steps to reproduce

Create the following items:

  • _bbb
  • aaa
  • ccc

And then sort them by title.

The item “_bbb” is moved between “aaa” and “ccc”, which is not what used to happen until a few months ago.

The “_” character (and other non-alphanumeric characters such as “@”) where ordered before the alphanumeric characters.

This is a feature I rely on heavily. I don’t know how else to have some items kept on top of the list when all the others are sorted alphabetically.

Environment

On Kubuntu, destop app or Chrome.
