The cost of such exceptions is that an application cannot reliably use the general categories to detect, evaluate or create numbers in a relevant script. So this requires a separate table for each supported script. This unnecessarily complicates algorithms that support internationalized numeric strings, in a area where it could be very simply fixed. We do need that characters that have a numeric property be defined either as "Nd" (with three non-empty numeric properties values), or "Ni" (with two non-empty numeric properties values), or "Nl" (with one non-empty numeric properties values) or "No", i.e. "Number, Other" (with no non-empty numeric properties), and that NO other category than "Mn" can have non-empty numeric properties. > >BTW I've just noticed that U+10341 has a general category of > "Lo" (Letter, > >Other), whereas U+1034A has a general category of "Nl" (Number, > Letter), which > >seems a little odd. > > It does.
