Beginner Question - ?/

Hey guys

Found a strange piece of code I haven't run into before.

     def redirect_to_directory_uri(req, res)
        if req.path[-1] != ?/
          location = req.path + "/"
          if req.query_string && req.query_string.size > 0
            location << "?" << req.query_string
          end
          res.set_redirect(HTTPStatus::MovedPermanently, location)
        end
      end

It's the "?/" on the second line that I don't understand. The only other
place I can find this is in one of the required files (used in the same
way) or at the end of a regular expression, but this is clearly not. I
have no idea what it is. Can anybody help?

And just in case this was a little cryptic, ?SOME_CHARACTER is the ruby equivalent of C's 'SOME_CHARACTER' or Lisp's #\SOME_CHARACTER
