See http://docs.python.org/2/library/functions.html#unicode. It appears to me
that unicode() is behaving exactly as documented. In particular:
If encoding and/or errors are given, unicode() will decode the object which
can either be an 8-bit string or a character

In the implementation of the PEP 446, issue #18571, I replaced
multiprocessing.util.pipe() with os.pipe() in the multiprocessing module.
Can we remove the multiprocessing.util.pipe() function? It is not public nor
documented.

I guess you could remove util.pipe() altogether: it wasn't part of the public
