diff Include/unicodeobject.h @ 18280:0632dcd69ea3 legacy-trunk
experimental UCS-4 support: added USE_UCS4_STORAGE define to
unicodeobject.h, which forces sizeof(Py_UNICODE) == sizeof(Py_UCS4).
(this may be good enough for platforms that doesn't have a 16-bit
type. the UTF-16 codecs don't work, though)
