(You're talking about things like "test" vs. "t&#x65;st" or CDATA
sections in XML, or "test" vs. "t%65st" in URIs, right?)

I don't think that any filtering can _ever_ be reliable without 
interpreting the raw data the way it is meant to be interpreted. 

(It's like trying to check for ".." segments in URLs that will be passed 
to a shell without checking for backslashes that the shell will interpret.
You might catch the URL "http://host/subsection/../.." but you'll miss
"http://host/subsection/\.\./\.\.".)
