The problem is that subprocess encodes PYTHONWARNINGS environment variable
value with the filesystem encoding, whereas Py_main() decodes the variable
value with the locale encoding.
History of how the variable is read in py3k:
- #7301: r79880 creates this variable, use mbstowcs() and PySys_AddWarnOption()
- #7301: r80066 uses setlocale(LC_ALL, ""), and replaces mbstowcs() by
_Py_char2wchar() (to support surrogates)
- #8589: r81358 creates PySys_AddWarnOptionUnicode() and replaces
_Py_char2wchar() by PyUnicode_DecodeFSDefault()
- #8589: r84694 replaces PyUnicode_DecodeFSDefault() by _Py_char2wchar() +
PyUnicode_FromWideChar() "because the PyCodec machinery is not ready yet"
- #8589: r84731 uses PyUnicode_FromString() (utf-8) on Mac OS X
