Subject: [PATCH] Update anti_ddos_challenge.lua

Big Fix :
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Malformed_URI
URIError: The URI to be encoded contains invalid character (Edge)
URIError: malformed URI sequence (Firefox)
URIError: URI malformed (Chrome)

To prevent this happening on my Hex encryption of javascript "\x char" and "%" char values a soloution is to use `unescape()` or `escape()` i decided to escape values.
