Send StringBuilder Contents over a Socket

Demonstrates Socket.SendSb, which encodes the contents of a StringBuilder using StringCharset and sends the resulting bytes.

Background. Text send and receive operations encode and decode bytes using the StringCharset property. For plain ASCII or UTF-8 protocols, setting StringCharset to utf-8 is a safe default.
