No, the configure options are wrong - we do use UTF-16 and UTF-32. 
Although modern UCS-4 has been restricted down to the range of UTF-32
(it used to be larger!), UCS-2 still doesn't support the supplementary
planes (ie no surrogates.)

If it really was UCS-2, the repr wouldn't be u'\U00010123' on windows. 
It'd be a pair of ill-formed code units instead.
