* 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 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
