-exec(compile(open(__file__).read().replace('\\r\\n', '\\n'), __file__, 'exec'))
+exec(compile(open(__file__,encoding='utf_8').read().replace('\\r\\n', '\\n'), __file__, 'exec'))

The fix is not correct, the script may use a different encoding.

Replace open() with tokenize.open(), available since Python 3.2.

.replace('\\r\\n', '\\n') is probably useless in Python 3 which uses universal newlines by default.
