Need to filter the request urls

Ok, I am implementing a tagging system like man sites have, for example del.iciou.us

I'll have a lot of traffic from non-english speaking countries.

What should I allow and what should I not allow in a tag? I was thinking of allowing multiple word tags. Any thoughst advces on that?

But I think the way I can make a clear question is:

Which chars should I block if I want to support pretty much every language out there?

Also, by using urlencode() do I make sure I can pick whatever was put in the url the exact same way as it was before? Or is there some glitches i should know about?
