i18n routes can't be recognized

Reported by Igor | June 18th, 2010 @ 06:50 AM | in 3.0.6

Rails (2.3.5 and it seems the same is with edge) with Ruby 1.9 correctly creates and stores utf-8 based routes. But when it comes to route recognition, it fails to match the route name:

map.home 'начало', controller: :home, action: :index


No route matches "/%D0%BD%D0%B0%D1%87%D0%B0%D0%BB%D0%BE" with {:method=>:get}

The reason is that recognize_path does html unescape only after routes are mapped, and because of this it fails to map raw utf8 stored name against its %XX%XX equivalent.

In 2.3.5 the next patch fixes the issue:

require 'action_pack'
require 'cgi'
module ActionController::Routing
  class RouteSet
    alias_method :recognize_path_ugly, :recognize_path

    def recognize_path(path, environment)
      path = CGI::unescape(path).force_encoding('utf-8').encode(invalid: :replace)
      recognize_path_ugly(path, environment)

The problem was introduced with which basically tried to fix another issue. Actually fixing it with the above patch will break the current behaviour of parameters unescaping, so it should be carefully considered.

The similar issue was raised which also may interfere with this problem:
