URL Escape Code

1. URL escape codes are sequences of ASCII characters which represent either non-ASCII characters or URL reserved characters.
   • A URL escape code is a 3 character sequence. The first character is always %, and it is followed by a 2 character hexadecimal number.
   • To prevent URL reserved characters from being treated as such in URLs, they must manifest as URL escape codes.
   • For non-ASCII characters to be included in URLs they must manifest as URL escape codes.
