(Go) Setting the MIME Text Charset (such as utf-8, iso-8859-1, etc.)

Demonstrates how setting the Charset property controls the character encoding used for the text body in a MIME message.

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

    mime := chilkat.NewMime()

    // Set the MIME body using some 8bit non-us-ascii characters:
    mime.SetBody("á, é, í, ó, ú")

    // Set the Content-Type
    mime.SetContentType("text/plain")

    // Set the Content-Transfer-Encoding to "quoted-printable"
    // so it's easy to see the bytes used to encode each character
    // (i.e. it will be easy to see that utf-8 uses 2-bytes for 
    // non-us-ascii characters such as "á", whereas a character
    // encoding such as iso-8859-1 will use one byte per character.
    mime.SetEncoding("quoted-printable")

    // Set the Charset to utf-8
    mime.SetCharset("utf-8")

    // Examine the MIME:
    fmt.Println(*mime.GetMime())

    // The MIME should look like this:

    // Content-Transfer-Encoding: quoted-printable
    // Content-Type: text/plain; charset="utf-8"
    // 
    // =C3=A1, =C3=A9, =C3=AD, =C3=B3, =C3=BA

    // Now change the Charset to "iso-8859-1"
    mime.SetCharset("iso-8859-1")

    // Get the MIME again...
    fmt.Println(*mime.GetMime())

    // Now the MIME should look like this:

    // Content-Transfer-Encoding: quoted-printable
    // Content-Type: text/plain; charset="iso-8859-1"
    // 
    // =E1, =E9, =ED, =F3, =FA
