[issue19637] test_subprocess.test_undecodable_env() failure on AIX

[STINNER Victor]

New submission from STINNER Victor:

To analyze the following issue, I would like to know which locale encoding is used on AIX with the C locale. Example:

$ LC_ALL=C python -c 'import locale; print(locale.getpreferredencoding(False))'
ANSI_X3.4-1968

http://buildbot.python.org/all/builders/PPC64%20AIX%203.x
