In the case of NumPy it was so that String and Unicode arrays would both
look like multi-length string "character" arrays and not arrays of
arrays of some character.
But, this can change in the data-format object. I can see that the
Unicode description needs to be improved.

Yes, you are correct. A string of unicode characters should really be
represented in the same way that an array of integers is represented for
a data-format object.
