backslashreplace is also the default errors for stderr, which is 
arguably the right target for debugging output. Perhaps what we really 
want is a shorter way to send output to stderr? Though I guess it's an 
easy to invent one-liner, once you know about the difference:

 >>> printe = partial(print, file=sys.stderr)

Also worth noting that Python 3.6 supports Unicode characters on the 
console by default on Windows. So unless sys.stdout was manually 
constructed (a possibility, given this was a GUI app, though I designed 
the change such that `open("CON", "w")` would get it right), there 
wouldn't have been an encoding issue in the first place.
