URL-Encode a MIME Body

Demonstrates the Chilkat Mime.UrlEncodeBody method, which replaces the current body with an application/x-www-form-urlencoded-style representation using the named charset. The only argument is the charset; it is a void method.

Background: This transforms the body into the form-encoding used by HTML form submissions — spaces to +, reserved characters to percent-escapes — interpreting the text through the given charset first so non-ASCII characters encode correctly. It is a niche operation for constructing form-style payloads within a MIME part.
