plane-1 support in (java|ecma)script

Does anyone know what the status is of support for plane-1 unicode  
characters in ECMAScript?  There seems to be no concept of characters  
greater than \uxxxx in any of the implementations I've tried  
(Firefox, Safari, IE) and nothing in the ECMAScript 3 spec.  The  
email address of the maintainer for the Javascript 2.0 proposal on  
Mozilla's pages bounced, so I'm not sure where to go next.  I'd like  
to know if there's any likelihood of support for characters in the  
range \uxxxxxx anytime in the near future.

Help?

Thanks,
Hugh Cayless
