    var sb = new chilkat.StringBuilder();

    // URL encode the string.
    sb.Encode("url","utf-8");

    // Show the URL encoded string:
    var sEncoded = sb.GetAsString();
    console.log(sEncoded);

    // The result is:  Why%20a%20%3E%20b%3F

    // If you prefer "+" instead of "%20" for SPACE chars:
    var numReplaced = sb.Replace("%20","+");
    console.log(sb.GetAsString());

    // Output is:   Why+a+%3E+b%3F

    // To decode:
    sb.Decode("url","utf-8");
    console.log(sb.GetAsString());

    // Result is: Why a > b?
