I just figured out why not.

As I understand it, the internal issue isn't whether the scalar value 
(such as U+E000) can be represented in 16 bits, but whether the UTF-8 
character can be represented in 16 bits.  Have a look at page 47 of

The UTF-8 representation of 0xE000 is
	11101110 10000000 10000000
which isn't 16 bits.

Are there any other holes in lower Unicode that could be exploited?  
How badly do we want this?
