Then I don't understand why we need to worry about encoding.  IP
addresses are pure ASCII strings, so they need no encoding whatsoever.

I guess I will have to ask you to back up and describe what problems
you saw with the original code, and show me the details of the strings
involved in that.

Thanks for the rest of your message, but I suggest that we limit
ourselves to IP addresses for the time being, and only go to non-ASCII
domains when we have the IP address use case figured out.
