talking squares

When you see foreign text but your browser does not have that character/font encoding, so instead of seeing Chinese/Sanskrit/Russian characters, all you see are squares.

To best handle this situation, just type squares back from your side of the conversation/forum/etc.

a)I can't understand this guy I'm chatting with. He's just talking squares.

b)Our forum got invaded by talking squares. I think they're talking about us but I can't be sure.

c)Talking squares, my WPM is over 9000.
