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

      Example:
          * Input: SELECT FIELD%20FROM TABLE
          * Output: %u0053%u0045%u004c%u0045%u0043%u0054%u0020%u0046%u0049%u0045%u004c%u0044%u0020%u0046%u0052%u004f%u004d%u0020%u0054%u0041%u0042%u004c%u0045'
  
      Requirement:

          * Microsoft SQL Server 2005
          * MySQL 5.1.56
          * PostgreSQL 9.0.3
