Unicode-url-encodes non-encoded characters in a given payload (not

    Requirement:
        * ASP
        * ASP.NET

    Tested against:
        * Microsoft SQL Server 2000
        * Microsoft SQL Server 2005
        * MySQL 5.1.56
        * PostgreSQL 9.0.3

    Notes:
        * Useful to bypass weak web application firewalls that do not
          unicode url-decode the request before processing it through their
          ruleset
