// This function provides the same conversion as that obtained from
// java.net.URLEncoder.encode().  The function converts a string into
// the x-www-form-urlencoded MIME format.
//
// To convert the string, each character is examined in turn:
//
//     o The ASCII characters 'a' through 'z', 'A' through 'Z',
//       '0' through '9', and '.', '-', '*', '_' remain the same.
//     o The space character (' ') is converted into a plus sign ('+').
//     o All other characters are converted into the 3-character string
//       %XY, where XY is the two-digit hexadecimal representation of the
//       lower 8-bits of the character.
//
// NB: The list of characters that are not encoded have been determined by
//     referencing O'Reilly's "HTML: The Definitive Guide" (page 164).
//
// The implementation is derived from that found at
// <http://summerholiday.org/freecode/JavaScript_URL_Encode.html>
// (which appears to share significant DNA with the code at
// <http://www.blooberry.com/indexdot/html/topics/urlencoding.htm>).
