It's not a bug. The problem isn't even the decode statement. Python
successfully creates the unicode string '\ufffdabc' and then tries to
print it to the screen. so it has to convert it to cp437 (your console
encoding) which fails. That's why the traceback mentions the cp437
file and not the utf-8 file.
