+``u`` (Unicode) [Py_UNICODE \*]
    Convert a Python Unicode object to a C pointer to a NUL-terminated buffer
    of 16-bit Unicode (UTF-16) data.  As with ``s``, there is no need to
    provide storage for the Unicode data buffer; a pointer to the existing
    Unicode data is stored into the :ctype:`Py_UNICODE` pointer variable whose
    address you pass.
 
-``u#`` (Unicode object) [Py_UNICODE \*, int]
+``u#`` (Unicode) [Py_UNICODE \*, int]
    This variant on ``u`` stores into two C variables, the first one a pointer
    to a Unicode data buffer, the second one its length. Non-Unicode objects
    are handled by interpreting their read-buffer pointer as pointer to a
    :ctype:`Py_UNICODE` array.
