Either '+' or %20 is legitimate - the Technorati spider supports plain 
spaces in the url too, but this is a Postel's law implementation, not 
recommended behaviour.

Encoding non-english languages in URLs is clearly specified in RFC 
3986. I've updated the spec to clarify this - thanks for the feedback. 
(tip - the technorati tags pages will show you the right URL for any 
unicode you type in)
