function chilkatExample() {

    var sb = new chilkat.StringBuilder();

    sb.Append("backslash: \\\\, A: \\u0041");
    console.log(sb.GetAsString());

    // The output is:
    //    backslash: \\, A: \u0041

    // The keyword "json" can be used
    // to escape and unescape.  To escape is to encode.  To unescape is to decode.

    // Unescape (decode) the string in sb.
    sb.Decode("json","utf-8");
    console.log(sb.GetAsString());

    // After JSON unescaping:
    //    backslash: \, A: A

    // Now JSON escape the string.
    sb.Encode("json","utf-8");
    console.log(sb.GetAsString());

    // After JSON escaping:
    //    backslash: \\, A: A

    // Note: The "A" is not escaped to "\u0041" because there is no need.
    // The "\uXXXX" format would be produced for non-printable control chars.
