NumPy can create boolean arrays out of strings, but cannot convert string arrays to bool_. I think we should follow Python here and assign truth values to strings.

Reproducing code example:

>>> import numpy as np
>>> np.array('N', dtype='?')
array(True)
>>> np.array('N').astype('?')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'N'

Error message:
