It would be straight forward to have such a tree string representation where some segments have 16-bit cells and others 32-bit (or even 8-bit) cells. That is probably how I would present any long string that that contained only a few supplemental characters.

I'm not talking about the implementation end.  I can see how I'd 
implement this stuff, or make Luke implement it or something.  What I 
don't see is how the JS program author can sanely work with the result.
