rails session store和UTF8

Question

我遇到涉及rails会话存储和UTF8的问题。似乎当我将一些来自Omniauth的变量保存到我的会话中时，我之后得到了ASCII-8BIT。

我在我的applications.rb文件中设置了UTF8，UFT8在其他任何地方都能正常工作。

application.rb中

config.encoding = "utf-8"

session_store.rb

Wombieapp::Application.config.session_store :cookie_store, :key => '_wombieapp_session'

野外

last_name.encoding.name
"UTF-8"

使用Rails 3.0.10。

从会话中返回ASCII-8BIT

omniauth: {"provider"=>"google_apps", "uid"=>"https://www.google.com/accounts/o8/id?
id=AItOawlx217kz5Tkid0sq5_jIzHGQKupMDI6COc", 
"user_info"=>{"email"=>"someemail@gmail.com", "first_name"=>"Joe", 
"last_name"=>"Mc\xC3\x99isnean", "name"=>"Joe Mc\xC3\x99isnean"}}

应该是（会前原创）：

"omniauth"=>
  {"user_info"=>
    {"name"=>"Joe McÙisnean",
     "last_name"=>"McÙisnean",
     "first_name"=>"Joe",
     "email"=>"someemail@gmail.com"},
   "uid"=>
    "https://www.google.com/accounts/o8/id?id=AItOawnQmfdfsdfsdfdsfsdhGWmuLTiX2Id40k",
   "provider"=>"google_apps"}

的Gemfile

#core
gem 'rails', '3.0.10'
gem 'pg', '0.11.0'
gem 'simple_form'
gem 'client_side_validations'

#authorization
#gem 'devise', '1.4.2'
gem 'devise', '1.2'
gem 'omniauth', '0.2.6'
gem 'rails_admin', :git => 'git://github.com/sferik/rails_admin.git', :branch => 'rails-3.0'

#heroku
gem 'heroku'
gem 'redcarpet'
gem 'resque', '~> 1.17.1', :require => 'resque/server'
gem 'resque-meta', '1.0.3'
gem 'resque-async_deliver'
gem 'resque-heroku-autoscaler', '~> 0.2.3'

还尝试将Encoding添加到environment.rb

的environment.rb

Encoding.default_internal = 'UTF-8'
Encoding.default_external = 'UTF-8'

# Initialize the rails application
Wombieapp::Application.initialize!

我也尝试手动将其粘贴在会话中

session[:omniauth] = {"user_info"=> {"name"=>"Joe McÙisnean", "last_name"=>"McÙisnean", "first_name"=>"Joe", "email"=>"someemail@gmail.com"}}

并出现ASCII错误
