Mixed Script Arithmetic

Greetings All,

  I ran into a problem recently with the issue of mixed script arithmetic and I
realized that the numeric property identifiers (Nd, No, Nl) were not informative
as to what numerical (or numeric-like) characters could be used in integer
arithmetic.

  For example are CIRCLED DIGITS or PARENTHESIZED DIGITS appropriate here? I've
made the following table for consideration in the UniData "Props.txt" file. I
have made my best guess as to what may be used in different mathematic
practices, corrections and extensions are certainly in order.
