+
+   The ``'u'`` typecode corresponds to Python's unicode character.  On narrow
+   Unicode builds this is 2-bytes, on wide builds this is 4-bytes.

 The actual representation of values is determined by the machine architecture
 (strictly speaking, by the C implementation).  The actual size can be accessed
 through the :attr:`itemsize` attribute.
