how to encode an exclamation mark in an url?

I have been trying to encode an ! in an url, but somehow it just doesn't work.

I tried RFC1738 codes -- one website mentioned the code was %21, a couple others said it was %22. However, both don't do any good.

Any pointers?

I get it as %21 using perl's uri encoder

$ echo -n '!' | perl -MURI::Escape -le 'print uri_escape <STDIN>'
%21

Can you encode "~", "#", "?" etc.?

W3C is a very good resource for html and css, they say to encode ! as !

I don't think you use html escape codes in urls.

I agree with %21.  You can also look it up at http://www.w3schools.com/tags/ref_urlencode.asp or use their "Try It Yourself" form.
