Title: Support unicode character route in config/routes.rb.

Support unicode character route in config/routes.rb, e.g.:

get 'こんにちは', :controller => 'home', :action => 'index'

In current Rails, we had to draw encoded route, e.g.:

get Rack::Utils.escape('こんにちは'), :controller => 'home', :action => 'index'
