This file contains more detailed doctests for the stdnum.by.unp. It
tries to cover more corner cases and detailed functionality that is not
really useful as module documentation.

>>> from stdnum.by import unp

'591705582'
>>> str(unp.validate(u'\u0423\u041d\u041f 591705582'))
'591705582'
>>> unp.validate('UNP 591705582')
'591705582'
