Demonstrates how to Q and B encode/decode. Swift

    var success: Bool = false

    let sb = CkoStringBuilder()!

    sb.append(value: "This is a test")

    print("\(sb.getEncoded(encoding: "B", charset: "utf-8")!)")

    print("\(sb.getEncoded(encoding: "Q", charset: "iso-8859-1")!)")
    // output is:

    // output is:
    // This is a test

    // "B" or "Q" will decode both B and Q.
