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'd like some opinions on these "real" Unicode questions from some of > the experts who normally stay away from PUA issues, and especially > from the CSUR. I'm sure that Philippe will be more than happy to share some of his weighty opinions on this matter. Andrew
