- A new pickle protocol (protocol 3) is added with explicit support
for bytes. This is the default protocol. It intentionally cannot
be unpickled by Python 2.x.
- When a pickle written by Python 2.x contains an (8-bit) str
instance, this is now decoded to a (Unicode) str instance. The
encoding used to do this defaults to ASCII, but can be overridden
via two new keyword arguments to the Unpickler class. Previously
this would create bytes instances, which is usually wrong: str
instances are often used to pickle attribute names etc., and text is
more common than binary data anyway.

- Default to ASCII as the locale.getpreferredencoding, if the POSIX
system doesn't support CODESET and LANG isn't set or doesn't
allow deduction of an encoding.
