Ah, interesting.  But with numbers/money/dates each able to be separately 
configured rather than an all-or-nothing, that would seem an ideal fit, rather 
than having a special exception?

Doing some more research makes it clear we can't do Hebrew numbers as they are 
not a decimal digit system as supported by DigitSet and Unicode:

http://www.i18nguy.com/unicode/hebrew-numbers.html

In Unicode the following decimal digit sets are apparently supported with the 
numeric value property, Hebrew isn't so won't work:

  Arabic, Balinese, Bengali, Devanagari, Ethiopic, Gujarati, Gurmukhi, Telugu,
  Khmer, Lao, Limbu, Malayalam, Mongolian, Myanmar, New Tai Lue, Nko, Oriya,
  Telugu, Thai, Tibetan, Osmanya

(Any plans to support them all?  I think we can ignore the Ancient Greek, 
Roman and Cuneiform number systems :-)

I wonder if we should special case this in KLocale or the KCM to allow the 
choice for Date Digit Set only?  It's probably not a good user experience to 
see the Date Digit Set in System Settings as one value, but have the calendar 
use another?  

I guess that's for 4.5 to sort out, for 4.4 I'll do the hack.

John.
