Looks like "что это", "what's this" in Russian. It may be seen when a Russian server player has the US keyboard and does not have the same characters. This is the most likely result.
A Russian dude: 4to 3to
A US dude: wot?
The Russian dude: Aw frick, I forgot to switch my keyboard lol
Also the Russian dude 1 minute later: что это
The US dude: Communist detected on American soil. Lethal force engaged.
