In 1.13 and master

>>> arr = np.array([' ', ' ', ' '], np.unicode_)  # or bytes_
>>> arr.nonzero()
(array([], dtype=intp),)
>>> np.count_nonzero(arr)
0
>>> np.count_nonzero(arr, axis=0)
3  # but wait, maybe ' ' is truthy after all!

Apparently in some cases ' ' is considered true, yet in others it is considered false. (cause: #9875)
