    }

    //  For example, let's say we want construct simple JSON containing the base64 representation of the above JPG file.
    CkStringBuilder sb;
    sb.Append("{ \"jpg\": \"");
    //  GetEncodedSb appends the enocded representation of the binary data to the StringBuiler passed in the 2nd arg.
    bd.GetEncodedSb("base64",sb);
    sb.Append("\" }");

    std::cout << sb.getAsString() << "\r\n";

    //  Output looks like this:
    //   { "jpg": "/9j/4AAQSkZJRgABAg...rcQ+vo//2Q==" }
