What are the chars that the url can include?

It doesn't solve the problem, but I think I have another direction.

The route of my article page is:

Code:

$route['news/(:any)'] = 'news_ci/article/show/$1';

Code:

http://www.domain.com/news/name-of-article/
http://www.domain.com/news/name-of-article/asd/wew/sda/ ..

Both of these address work, when I need that just address no.1 will work.

Maybe there is a problem with the .htaccess file? I found this code in the net and used it (and don't see a problem with the code):

Code:

RewriteEngine On

    RewriteBase /

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.

    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)/$ /index.php?/$1 [L]
    
    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.

    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)/$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ index.php/$1 [L]
