    Looking at the examples shown on
    <http://en.wikipedia.org/wiki/John_W._Nystrom>, it seems to me that
    0-8 are ordinary digits, and the symbols for 9 through 15 are inverted
    or inverted+modified forms of the digits '7' through '1', so that
    there is some sort of imperfect bilateral symmetry on the clock and
    compass faces, with '0' and '8' as the axis of symmetry. Thus the '9'
    is an inverted '6' (as 16-6=10) not an ordinary '9'. So except for the
    odd glyph forms for 9, 11, 12 and 15 (would be be expected to be
    simple inversions of '7', '5', '4' and '1') it makes sense as a system
    to me.

    Anyhow, I do not think the ordinary digits '0' through '8' should be
    encoded in the CSUR.

    I'm sure that Philippe will be more than happy to share some of his
    weighty opinions on this matter.
