instead of surrogateescape

So it would be possible to support more error handlers later.

Add also FIXMEs in unicodeobject.c

 * Use PyUnicode_EncodeLocale() in time.strftime() if wcsftime() is not
   available
 * Document my last changes in Misc/NEWS

 * PyUnicode_DecodeLocaleAndSize() and PyUnicode_DecodeLocale() decode a string
   from the current locale encoding
 * _Py_char2wchar() writes an "error code" in the size argument to indicate
   if the function failed because of memory allocation failure or because of a
   decoding error. The function doesn't write the error message directly to
   stderr.
 * Fix time.strftime() (if wcsftime() is missing): decode strftime() result
   from the current locale encoding, not from the filesystem encoding.
