¿Es posible establecer una cadena Unicode como un segmento de una ruta en Rails?

Intento lo siguiente:

  
# app/controllers/magazines_controller.rb

class MagazinesController < ApplicationController
  def index                                     
  end                                                                           
end
  

  
# encoding: utf-8
# config/routes.rb

PublishingHouse::Application.routes.draw do
  resources :magazines,
    :only => :index,
    :path => :журналы # a Unicode string is set as a segment of the path
end
  

$ rake routes
magazines GET /журналы(.:format) {:action=>"index", :controller=>"magazines"}

Pero cuando voy a la ruta me sale el error de enrutamiento:

$ w3m http://localhost:3000/журналы
...

Routing Error

No route matches "/%D0%B6%D1%83%D1%80%D0%BD%D0%B0%D0%BB%D1%8B"

Aquí está el registro del servidor:

$ rails s thin
...

Started GET "/%D0%B6%D1%83%D1%80%D0%BD%D0%B0%D0%BB%D1%8B" for 127.0.0.1 at 2010-09-26 13:35:00 +0400

ActionController::RoutingError (No route matches "/%D0%B6%D1%83%D1%80%D0%BD%D0%B0%D0%BB%D1%8B"):

Gracias.
