CodeIgniter中的allowed_uri_chars问题

I am facing issue with permitted_uri_chars in CodeIgniter. Followig is my config:

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_-()@!';

As per my config the Special Symbols should be allowed. It work for symbols but when I use the Symbols in combination it don't work.

Scenario:

http://localhost/ci/test/index/page(new).html

When my URL as above i am getting the error:

An Error Was Encountered

The URI you submitted has disallowed characters.

But following works fine.

http://localhost/ci/test/index/page(new.html

http://localhost/ci/test/index/pagenew).html

How can I solve this issue? I don't wish to solve this issue using .htaccess !!

@TomPHP Please put the below characters in your config.php file.

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-()@!';

You forgot to put \ in allowing character that raise issue for uri.

Try adding this. works for me.

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-()@!';
