if the parameter value has slash, how can i pass it to codeigniter url

[eluser]searain[/eluser]
For example, the parameter value is "dump / dummer"

I want to pass this parameter value to the codeigniter site, http://mycisite.com/get/.

http://mycisite.com/get/dump / dummer

Of course, it would not work

urlecode('dump / dummer') and then pass it to http://mycisite.com/get/ still not work.

Thanks!
