codeigniter routed segments incorrectly converting dashes to underscores with nginx

He shouldn't have to extend anything. It works fine on Apache, something with Nginx is messing with it.

I've never used Nginx, so I'm not much help. I can tell you, though, that the start/end characters in your route regex are unnecessary - Router.php will put them in for you.
