Disallowed Key Characters that don't seem to be able to fix in config

Actually the problem is that Input.php specifically on te line 217 is not taking into account the permited_uri_chars config parameter, why?, it appears to me a bug, so, you can change that line by this:

if ( ! preg_match("/^[" . config_item('permitted_uri_chars') . "]+$/i", $str))

And now you can add all your chars to that parameter and it will be taken into account.

In my case, I was having problems with ' and \, cause I send an array (ie I have one table grid with names like row[0][description]).

My english is not good enough cause I'm not an english spoken person, sorry XD

Bye!

Also note that if you want to escape a \ (backslash) you need to put four backslashes in your permitted_uri_chars parameter like this:

$config['permitted_uri_chars'] = 'a-z\s0-9~%.:_\-\'\\\\';
