    String sEncoded = sb.getAsString();
    Log.i(TAG, sEncoded);

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

    // If you prefer "+" instead of "%20" for SPACE chars:
    int numReplaced = sb.Replace("%20","+");
    Log.i(TAG, sb.getAsString());

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

    // To decode:
    sb.Decode("url","utf-8");
    Log.i(TAG, sb.getAsString());

    // Result is: Why a > b?
