Inputting ° has strange side effects

° can't be inputted directly from the keyboard.
However, inputting it causes crashes and side effects.
If inputted while in the shell, it prints an error and shuts down the computer.

If inputted while editing a program, it prints the error and returns to the shell. However, the screen is not cleared.

That symbol is not supported by all versions of computercraft. The behavior before a certain version would be to simply replace it with a '?'. However, when blit was added things got messed up. It's been fixed in later versions, IIRC.

you can try using lua and doing "term.redirect(term.native()) shell.run("edit eprogram")" in the same cpmmand line and it will replace unknown characters with ?
