CodeIgniter cyrillic url routing

[eluser]0v3rth3d4wn[/eluser]
Hi! I'm having the following problem. I want to use cyrillic symbols in the url. Actually CI is allowing me to use them for a parameter, but not for routing.

On my previous project my config was:

Code:

$config['permitted_uri_chars'] = 'a-z 0-9~%&.:_\-абвгдежзийклмнопрстуфхцчшщьъюя';

And everything was working fine and I was able to do this:

Code:

$route['контакт'] = "contact";

But now I can't do it. It gives me an 404 page when using the same configs. The weird thing is that I can use cyrillic chars for method attributes, but I can't route them right now. I read in the forum that I should encode them. So this is working:

Code:

$route[urlencode('контакт')] = "contact";

But this is silly. So I tried encode them in the config file and did this:

Code:

$cyrillic = array('а','б','в','г','д','е','ж','з','и','й','к','л','м','н','о','п','р','с','т','у','ф','х','ц','ч','ш','щ','ь','ъ','ю','я');
function enc(&$item)
{
$item = urlencode($item);
};
array_walk($cyrillic,'enc');
$config['permitted_uri_chars'] = 'a-z 0-9~%&.:_\-'.implode('',$cyrillic);

When I echo the imploded $cyrillic array it returns the encoded chars but my routing is still not working. Am I doing this right?

Thank you in advance!

1. Search in /system/core/URI.php

Code:

"]+$|i"

2. Replace on

Code:

"]+$|ui"

3. config.php

Code:

$config['permitted_uri_chars'] = 'a-zа-яё 0-9~%.:_\-';

Thanks for the reply, but this is not working for me. I'm still getting 404 page. It is weird because it isn't the "Unallowed chars error".
