[issue15648] stderr refs output does not respect PYTHONIOENCODING

[Georg Brandl]

Georg Brandl added the comment:

The refs output is only active in debug mode, and only for debugging. It is 
printed directly to stderr using C fprintf(), I don't think it's worth the 
complication.

[issue15648] stderr refs output does not respect PYTHONIOENCODING

[Chris Jerdonek]

New submission from Chris Jerdonek:

The --help documentation for the python executable says--

PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr.

However, PYTHONIOENCODING doesn't seem to be respected for the python 
executable's refs output to stderr.  For example, this--

args = [sys.executable, '-c', print('[100 refs]')]

env = {'PYTHONIOENCODING': 'utf-8'}
popen = Popen(args, universal_newlines=False, stdin=PIPE, stdout=PIPE, 
stderr=PIPE, env=env)
print(repr(popen.communicate()))

env = {'PYTHONIOENCODING': 'utf-16'}
popen = Popen(args, universal_newlines=False, stdin=PIPE, stdout=PIPE, 
stderr=PIPE, env=env)
print(repr(popen.communicate()))

yields--

(b'[10 refs]\n', b'[41761 refs]\n')
(b'[\x001\x000\x00 \x00r\x00e\x00f\x00s\x00]\x00\n\x00', b'[42367 refs]\n')
