def convert_numpy_str_to_uint16(data):
    """ Converts a numpy.unicode\_ to UTF-16 in numpy.uint16 form.

    Convert a ``numpy.unicode_`` or an array of them (they are UTF-32
    strings) to UTF-16 in the equivalent array of ``numpy.uint16``. The
    conversion will throw an exception if any characters cannot be
    converted to UTF-16. Strings are expanded along rows (across columns)
    so a 2x3x4 array of 10 element strings will get turned into a 2x30x4
    array of uint16's if every UTF-32 character converts easily to a
    UTF-16 singlet, as opposed to a UTF-16 doublet.

    Parameters
    ----------
    data : numpy.unicode\_ or numpy.ndarray of numpy.unicode\_
        The string or array of them to convert.

    Returns
    -------
    array : numpy.ndarray of numpy.uint16
        The result of the conversion.

    Raises
    ------
    UnicodeEncodeError
        If a UTF-32 character has no UTF-16 representation.
