Send UTF-16 on TCP or TLS Socket

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. Go

    success := false

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

    socket := chilkat.NewSocket()

    tls := false
    maxWaitMs := 20000
    domainOrIpAddr := "example.com"
    port := 1234

    // Connect to the whatever is expecting our connection...
    success = socket.Connect(domainOrIpAddr,port,tls,maxWaitMs)
    if success != true {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        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..
    sbXml := chilkat.NewStringBuilder()
    success = sbXml.LoadFile("qa_data/xml/myUtf16.xml","utf-16")
    if success != true {
        fmt.Println("Failed to load utf-16 XML file..")
        socket.DisposeSocket()
        sbXml.DisposeStringBuilder()
        return
    }

    // Tell the socket object that we wish to send the utf-16 byte representation of the string.
    socket.SetStringCharset("utf-16")

    // Send the string as utf-16 bytes.
    success = socket.SendSb(sbXml)
    if success != true {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        sbXml.DisposeStringBuilder()
        return
    }

    // Let's say we wanted to instead send the string as utf-8 bytes.
    // Just tell the socket object...
    socket.SetStringCharset("utf-8")

    // Send the string as utf-8 bytes.
    success = socket.SendSb(sbXml)
    if success != true {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        sbXml.DisposeStringBuilder()
        return
    }

    // If our XML file was utf-8, then just tell the StringBuilder that we're reading utf-8.
    // 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).
    success = sbXml.LoadFile("qa_data/xml/myUtf8.xml","utf-8")
    if success != true {
        fmt.Println("Failed to load utf-8 XML file..")
        socket.DisposeSocket()
        sbXml.DisposeStringBuilder()
        return
    }

    // Send as utf-16
    socket.SetStringCharset("utf-16")

    // Send the string as utf-16 bytes.
    success = socket.SendSb(sbXml)
    if success != true {
