Summary: getdefaultlocale failure on OS X

Initial Comment:
My OS X laptop did not have LANG  set in the bash
envrionment and idle (AquaTK) failed to launch with an
AttributeError in IOBinding.py

        try:
            encoding = locale.getdefaultlocale()[1]
            codecs.lookup(encoding)
        except (ValueError, LookupError):
            pass

encoding = encoding.lower()
^^^^^

encoding is None here because locale.getdefaultlocale()
returns (None, None) when the locale can't be determined.

After finding that adding LANG=en_US to my .bashrc
didn't help, I Iearned OS X GUI apps don't use the
shell's environment, but do use whatever they find in
~/.MacOSX/environment.plist.  Adding a couple lines:

        <key>LANG</key>
        <string>en_US</string>

makes idle happy.   An alternative would be to make
sure encoding never gets set to None.

Can you please find out how to determine the user's
prefererred encoding on OS X?

Yes, getdefaultlocale is broken, but that is by design, and
cannot be fixed. So we should reduce its usage instead of
trying to correct it.
