[Numpy-discussion] Getting number of *characters* in dtype='U' array

Is there a way to get the number of characters in a fixed-size 'U'
array? I can, of course, parse dtype.str, or divide dtype.itemsize by
the size of a unicode character, but neither seems terribly elegant or
future proof. Does numpy provide (to Python) a method for getting this
that I'm just missing?
In [7]: x = np.array(u'1234')
In [8]: x.dtype
Out[8]: dtype('<U4')
In [9]: x.dtype.str
Out[9]: '<U4'
In [10]: x.dtype.itemsize
Out[10]: 16
Cheers,
Mike
