At this point, I think we need not just "facts" but some
actual "design". Exactly how does this all work in a way that
actually solves the problem?

Let's suppose someone wants to publish information
about their product and put up a URL in a magazine.

a) what URLs do they support in their server?
b) what gets printed in the magazine?
c) what does the user type into the browser?
d) what does the browser do with what the user typed
   in order to turn it into the URL that was generated in (a).

how does this work for 
  1) Japanese (16-bit characters)
  2) Hebrew (right to left)

What happens with "/" and the path components? How does
directionality get represented? What are the considerations
for ambiguity beyond the familiar 0O0O0O1l1l1l for ASCII?

When the details of this are worked out, and we actually
have something that works to allow non-ASCII URLs, then
we can look and see if %xx-hex encoded UTF-8 encoded Unicode
actually forms part of the solution. But it doesn't seem
"trivial" to me, or at all certain that the current proposal
is actually part of the solution.

Larry
