Real solution? Set the command prompt to codepage 65001. Then it should be able to handle all characters.

Ultimately, it's going to depend on where your text is going: is it going to the console, or to a Tk widget? I don't have a Windows system handy to check, but I would suspect that you can distinguish these by seeing whether sys.stdout is a tty, since Idle pipes stdout into its own handler. That won't be a perfect check, as it would consider "piped into another command" to be UTF-8 compatible, but that's probably more right than wrong anyway.
