Dear Brian Eaton, --Monday, May 21, 2007, 6:22:21 PM, you wrote to websecurity () webappsec org: BE> If the SQL engine is processing queries in ASCII or ISO-8859-1, the BE> conversion from unicode to the code page used by the engine will fail.

At least for IIS: http://example.com/test.asp?q=%uFF1Cscript>alert("Hello")</script> where test.asp is <%=Request.QueryString("q")%> launches javascript. BTW: It may be used to bypass keyword based filtering to create, e.g. porn pages available through any corporate firewall.
