That's something I was curious about as well. I know parts of
Microsoft's version of the TDS protocol are done in Unicode. If you
pass the appropriate escape character in Unicode, the script
that's trying to strip out dangerous stuff wouldn't catch it.

The only problem I can see is how do you keep IIS from decoding the
Unicode first (talking about web form access, obviously.)
