Sorry, I misread the paragraph. It would be clearer to say URL creation mechanisms that generate the URL from a source which is not restricted to a single character->octet encoding are encouraged, but not required, to transition resource names toward using UTF-8 exclusively. URL creation mechanisms that generate the URL from a source which is restricted to a single character->octet encoding should use UTF-8 exclusively. If the source encoding is not UTF-8, then a mapping between the source encoding and UTF-8 should be used. And please cut the self-righteous crap in your replies. I am fully aware of why people want to localize their URLs, and I am in a better position to know what the implementation issues are when doing filename<->URL mapping. I have yet to see a memory+time efficient mapping from arbitrary charset to UTF-8, and I have a lot more faith in standards based on running code than on supposition. .....Roy
