Fix some encoding problems

python:

import locale;
import sys;

print(locale.getdefaultlocale())
print(locale.getpreferredencoding())
print(sys.getdefaultencoding())
print(sys.getfilesystemencoding())

php:

$locale = PyCore::import('locale');
$sys = PyCore::import('sys');
var_dump((string) $locale->getdefaultlocale());
var_dump((string) $locale->getpreferredencoding());
var_dump((string) $sys->getdefaultencoding());
var_dump((string) $sys->getfilesystemencoding());
