Nope, since "^C" is not a symbol (but two) and it is just one way of
visualizing it.
It happens under bash, actually the tty controlling program interprets
Ctrl+C and sends SIGINT (by default) to the process in foreground
(bash in this case); or does not and just prints "^C"

And there are quite a few ttys out there, so another idea would be to
confirm what is running in this troublesome system.
* hardware console (agetty, mgetty, mingetty, fbgetty, something else)?
* serial console
* some X11 implementation
