Except that this isn't possible.  The greatest number of codepoints that 
any font using current formats can support is 65k.  I'm pretty sure we're 
over that already, between points assign in the BMP & SMP.

It would be pretty nice if Sword could better handle switching fonts based 
on codepoint, but this seems logically to be best handled at render time 
by the layout engine in use (so it's probably best left to front-ends).  
The WebstersDict module actually isn't supported by any current font.  
Code2000 catches almost everything, but there are some musical symbols 
from the SMP that I have only seen in the Code2001 font.
