Well, in point of fact I think that %7e and %7E are the same in any 
rational world, and I think we should try to get there.

The namespaces spec says "character by character" largely because this 
issue hadn't occurred to us at that time.  I think that we could choose 
to reinterpret the term right now with generally beneficial effect and 
with minimal software breakage.

I also think that we could write down a set of carefully limited 
circumstances where software could un-%-escape before comparing, once 
again to beneficial effect and with minimal breakage.

Having said that, I'll have to go back and carefully re-read the 
dialogue between Martin/Misha/Chris to get a better understanding and 
find out if I'm wrong. -Tim
