Basically, I had my System Locale setting to Bulgarian, and that was affecting the font. Heres how it looked like before the fix.

And after the fix:

I changed the locale to English, and it warned me that I wont be able to use Bulgarian unicode characters after that.
But I applied changes, restarted PC, and i still can use them (явертъуиоп) They appear, they get sent on the internet correctly.
I hope I will help a lot of people fix this, because its really annoying. In my better editor mod, i coded a "THICC FONT" option that makes Courier bigger, but now that option is needless.
