Letter Ł displays awkwardly

The non-latin letter ł / Ł that I and my friends use for communication in polish doesn't display correctly in chat.

I've never before bothered to report it, frankly, because it's only a small nuisance and it's not game breaking BUT as Delirium league launched, the issue seemed to be solved! This really surprised and pleased me and my friends, more than it should.

But with the very first patch after launch, the change was reversed...



Here's how exemplary word zagłada (doom) looks in chat:



Hope it gets fixed again soon :)
