I'm testing a web application.  Previously, I had found XSS using a standard

not cause any problems).  I also URL encoded this same variant and it worked 
as well.  So I told them how to fix it (filtering out malicious characters, 
encoding, etc. on the server side) and it seems fixed now.  I was just 
curious if there is any other way to manipulate the same variant, such as 
other encoding schemes, that might bypass the protections I recommended.



Oh, lots. Why not do the right thing and block by default? Have a set of
valid character sets, and allow only a limited set of valid characters
in there?
