// Needs #include <CkMime.h>

    CkString strOut;

    CkMime mime;

    bool success;
    success = mime.UnlockComponent("Anything for 30-day trial.");
    if (success == false) {
        strOut.append(mime.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

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

    //  Set the Content-Type
    mime.put_ContentType("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.put_Encoding("quoted-printable");

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

    //  Examine the MIME:
    strOut.append(mime.GetMime());
    strOut.append("\r\n");

    //  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.put_Charset("iso-8859-1");

    //  Get the MIME again...
    strOut.append(mime.GetMime());
    strOut.append("\r\n");

    //  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
