If we absolutely must support unicode package names, we should do the URLs in PyPI in punycode and have pip show a puny-mangled name in a confirmation prompt for anything with non-ascii characters in it. Yes, that does basically remove all reason to use unicode in package names, which is why I think blocking it is a much better idea. [a-zA-Z0-9_.-] is probably the right way to go.

See my previous email where I did queries against my local DB. It's 225 total projects that wouldn't be allowed.
