You need to see when me and my friends start chatting in English written in Cyrillic. It's epic and utterly frustrating for the first hours, then becomes like native ;)
One of the other things that bugs the hell out of me is when in the late 90's during the boom of irc, here in Bulgaria everyone was writing in Bulgarian with latin script. And to make matters worse:
4 = ch
6 = sh
And some people keep on doing it. I can understand it when you have to switch between scripts every 2 seconds but most commonly that isn't the case and you are either having a conversation with someone or leaving it for later when you have time or when you feel like it...
Йес, съмтаймс уи ду дис то каунтър шльокавица ин партикюлър.
Edit: for the non initiates. It's this written in Cyrillic: "Yes, sometimes we do this to counter shlyokavitsa in particular"
Shlyokavitsa is the name of the forementioned style of writing Bulgarian with latin letters. The original meaning of the word is "low quality, self-made alcohol", possibly even poisonous because of methanol
