Title: Issue with fromarrays not using correct format for unicode arrays

If I understand correctly the records module is all but deprecated, so this is probably a bit obscure. But it came up in Astropy (see astropy/astropy#3052). This ensures that `np.rec.fromarrays`, and by extension `np.rec.fromrecords` uses the correct format for unicode arrays.
