Thanks for your suggestion, I have added two new options to my draft
proposal, one based on your suggestion (60 characters: 10 left, 10
middle and 10 right for normal and negative circles) and one more
verdyesque (four enclosing circle format characters).  To be honest, I
don't think the UTC will go for either of these options, but I doubt
they will be keen to accept any of the suggested options.

I have now added an example with circled ideographic numbers greater
than 100.  See Fig. 13 in


In this example, numbers greater than 100 are written in two columns
within the circle, with hundreds on the right.
