Add WebFix_URLEncode support
Browse files Browse the repository at this point in the history 
* Add urlencode 

URLEncode is necessary
Otherwise the redirection of the wrong  some address is in a particular case 
for example
https://bbs.93x.net/forum.php?mod=viewthread&tid=89686#newpost

https://csgottt.com/redirect.html?url=https://bbs.93x.net/forum.php?mod=viewthread&tid=89686#newpost
equal = https://bbs.93x.net/forum.php?mod=viewthread is an incorrect address

* Update webfix.inc
