See more Socket/SSL/TLS Examples

Demonstrates how to send a string on a connected TCP or SSL/TLS socket such that it is the utf-16 byte representation that is sent.

// Once the text is properly contained in the StringBuilder, we can send the contents in any other charset (windows-1252, utf-16, utf-8, etc.) 
// as long as it make sense (i.e. we obviously can't send Japanese text using a single-byte charset such as Windows-1252).
