By default in Python 3, check_output() returns a program's output as an encoded byte sequence. This means it returns a Py3 `bytes` object, which cannot be compared to a string since it's a different fundamental type. Although it might not be correct from a purist standpoint, from a practical one we can assume that all output is encoded in the default locale, in which case using universal_newlines=True will decode it according to the current locale. Anyway, universal_newlines also has the nice behavior that it converts \r\n to \n on Windows platforms so this makes parsing code easier, should we need that. So it seems like a win/win. llvm-svn: 252025
