/**
* Encode a string to the "x-www-form-urlencoded" form, enhanced with the UTF-8-in-URL proposal. This is what happens:
*
* <ul>
* <li>
* <p>
* The ASCII characters 'a' through 'z', 'A' through 'Z', and '0' through '9' remain the same.
*
* <li>
* <p>
* The unreserved characters - _ . ! ~ * ' ( ) remain the same.
*
* <li>
* <p>
* The space character ' ' is converted into a plus sign '+'.
*
* <li>
* <p>
* All other ASCII characters are converted into the 3-character string "%xy", where xy is the two-digit hexadecimal
* representation of the character code
*
* <li>
* <p>
* All non-ASCII characters are encoded in two steps: first to a sequence of 2 or 3 bytes, using the UTF-8 algorithm;
* secondly each of these bytes is encoded as "%xx".
* </ul>
*
* @param s The string to be encoded
* @return The encoded string
