Rails - Apr 2006 - URL encode & decode

I have a link:
<%= link_to ''delete'', :action =>
''destroy'', :id => u(string_id) %>

Helper method ''u()'' can encode a string to URL encoding, but I
don''t
know which method can decode it? I  want to used in controller. I have
not seen it in Rails''s document.

Thanks,

---------------------------------------------------------- CGI::unescape
      CGI::unescape(string)
------------------------------------------------------------------------
      URL-decode a string.

        string = CGI::unescape("%27Stop%21%27+said+Fred")
           # => "''Stop!'' said Fred"

(you will need

   require ''cgi''

in your controller)
