Since version 3.2, Python uses the locale encoding in PyUnicode_EncodeFSDefault() using _Py_wchar2char() and _Py_char2wchar() until the codec registry is initialized and the locale codec is loaded (until initfsencoding() is done).

Before Python 3.2, Python used ASCII in PyUnicode_AsEncodedString() at bootstrap (before the codec registry was initialized): we don't need this hack anymore and it is bad to use ASCII instead of the locale encoding (encode/decode can fail).

This ticket is just a reminder for me: I am waiting Python 3.3 to remove PyUnicode_AsEncodedString() bootstrap hack ;-)

Fixed by r88476. I prefer to only change it in Python 3.3, so no backport.
