(JavaScript) Send UTF-16 on TCP or TLS Socket

See more Socket/SSL/TLS Examples

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var socket = new CkSocket();

if (success !== true) {
    console.log(socket.LastErrorText);
    return;
}

// Let's say we have an XML file saved in the utf-16 byte representation,
// and we want to send it over the connection using the utf-16 byte representation...

// First the file into a Chilkat StringBuilder.
// Tell the LoadFile method that we are reading utf-16 bytes..

// Send the string as utf-16 bytes.

// 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).
