you found the hidden clue and solved it, first prize :)
They do not show up as gc=Nd, nor as numeric types Digit or Decimal.
The situation is worse than you indicate, because the same characters
are also used as elements in a system that doesn't use place-value, but
uses special characters to show powers of 10.
However, as I indicated in my original post, in situations like that,
there are usually some changes in practice that took place. Much of the
living modern practice in these countries involves ASCII digits. While
the ideographic numbers are definitely still used in certain contexts,
I've not seen them in input fields and would frankly doubt that they
exist there. I would fully expect that they are supported as number
format for output, at least in some implementations, and, of course,
that input methods convert ASCII digits into them. In other words, I
wonder whether automatic conversion goes only one-way for these numbers.
I would suspect it, for the general case, but I don't actually know for
For someone in Karl's situation, it would be interesting to learn
whether and to what extent he should bother supporting these numbers in
his language extension.
