PyUnicode_FromFormatV("%c") supposes that an unicode character is always stored as a single Py_UNICODE word: but that's wrong on narrow build with characters in [U+10000; U+10FFFF].
Attached patch fixes this bug.
See also bpo-10829.

Fixed in 3.3 (r88481).
Keep it open to backport it maybe to 3.2 later.

Fixed in 3.2 too (r88532).
