Summary: locale.getpreferredencoding fails on AIX

Initial Comment:

The problem is setting LC_CTYPE to an empty string:

>>> locale.setlocale(locale.LC_CTYPE, '')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/home/neal/python/dist/aix/Lib/locale.py", line 
381, in setlocale
    return _setlocale(category, locale)
locale.Error: locale setting not supported

Putting a try/except around the setlocale call in 
getpreferredencoding allows the test to pass.  I don't 
know if this is correct.

The problem was that the setlocale in Lib/locale.py was
being used, not from Modules/_localemodule.c.  In the python
version, it does not allow an empty string.  Seems like this
should be changed, do you agree?

What are the relevant environment settings? According to

http://nscp.upenn.edu/aix4.3html/libs/basetrf2/setlocale.htm

specifying "" as the second argument of setlocale is
supported, and means the same thing as it does on all other
systems: take locale settings from the user preferences.
