yes, its handled: WARNING: couldn't encode test.py's diff for your terminal is that fix specific to 2to3 or is that just how "print" works in 3.2 ? |

It's just that whatever python guesses your terminal encoding is (try print(sys.stdin.encoding)) might not be able to handle whatever characters are in the source file, so we just don't print it. You can change the default encoding with the PYTHONIOENCODING env var. |

You can just use the --no-diffs option, btw, to avoid this problem on earlier versions. |
