Routing with encoded params

[eluser]xylar[/eluser]
Hi,

I have the following route rule set in my config/routes.php:

Code:

$route["add/url/(:any)"] = "add/url/$1/$2/$3";

This works fine unless the params have encoded values so the following works:

Code:

http://site.com/add/url/true/www.google.co.uk/Google/

but this does not (without spaces):

Code:

http://site.com/add/url/true/http % 3 A % 2 F % 2Fwww.google.co.uk/Google/

It doesn't event seem to get to the controller function the page just says 'Object not found!'. What should I be doing?

Thanks.
