Need to filter the request urls

XML, Perl, Python, and other languages can be discussed here, even if it isn't PHP (We might forgive you).

Need to filter the request urls

Post by pedrotuga »

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?
