       I believe that's the case. (Note: they are not legal in the
       not-yet-I-don't-think-approved UTF-32.)

       Do they intent to deprecate private use characters in the
       ranges 00E00000
       to 00FF0000 and 60000000 to 7FFFFFFF?

       As far as I know, for the moment there are available for use,
       at least with UCS-4 (I understand they should be avoided if
       using UTF-32).
