My terminal shows unicode squares (the little square with it's 2 byte unicode value inside it), whenever I press a control character while running a program (ex. cat or ping).
See this example. Here I show the key's I pressed then turn off echoctl, and repeat the sequence. http://imagebin.ca/img/mXbutJ1.png
the 0003 is when I pressed Ctrl+C, and the 001A is when I pressed ctrl+z.
Can anybody tell me why this is or how to turn it off. This is inside a gnome-terminal session, though I don't think it's gnome-terminal.
If, inside this exact same bash session I open screen (by typing "screen"), it doesn't do this anymore, and ctrl+c/z/etc is completely quiet.
