Problem with route and URI Language code

[eluser]KeyStroke[/eluser]
Here's how I did it in my application:

Code:

$route['(en|ar|de|nl|es|fr|ru|pt)*/*(.*)'] = '$2';

I have valid language codes in my regex as you can see. This will route (for example) this:
http://example.com/ar/controller

to this:
http://example.com/controller

And you can still access the controller directly without problems.

Hope this helps.
