(SQL Server) HTTP GET with utf-8 URL Encoded Query Params

Demonstrates how to build URLs where query param values can be either URL encoded from the utf-8 representation, or from another charset such as windows-1252.

Note: This example uses the new DecodeAndAppend method added in Chilkat v9.5.0.87.
