Special Characters in Plasma

A good few years back, there was some work done to make adding special characters on Linux much easier in Plasma ;

Unfortunately it looks like it was reverted? Will we ever see this in Plasma 6? Until then, if anyone can just give me a clue on how to add special characters - umlauts, graves, etc, I’d be hugely grateful. Alt Key combos don’t seem to work.

:Edit: Looks like I was missing kcharselect

This feature ultimately had to be removed as it wasn’t compatible with the way input methods work in our space. This is a major topic that needs attention before really cool features like that can be landed.
