UTF-8 regexp with ASCII-8BIT string bug

[melezhik]

to reproduce:

• create project:

   cd /tmp/
   cucumber-nagios-gen project www.bbc.co.uk-russian
   cd www.bbc.co.uk-russian/
   cucumber-nagios-gen feature www.bbc.co.uk-russian bidding

• mcedit features/www.bbc.co.uk-russian/bidding.feature :

    Feature: www.bbc.co.uk-russian
         It should be up
  
             Scenario: Visiting home page
             When I go to "http://www.bbc.co.uk/russian"
             Then the request should succeed
             And I should see "Learning English"
             And I should see "Ресурсы Би-би-си"

• run feature: cucumber-nagios features/www.bbc.co.uk-russian/bidding.feature --pretty

  Feature: www.bbc.co.uk-russian
  It should be up
  
  Scenario: Visiting home page                  # features/www.bbc.co.uk-russian/bidding.feature:4

    Then the request should succeed             # features/steps/http_steps.rb:64
    And I should see "Learning English"         # features/steps/http_steps.rb:52
    And I should see "Ресурсы Би-би-си"         # features/steps/http_steps.rb:52
      incompatible encoding regexp match (UTF-8 regexp with ASCII-8BIT string) (Encoding::CompatibilityError)
      ./features/steps/http_steps.rb:53:in `/^I should see "(.*)"$/'
      features/www.bbc.co.uk-russian/bidding.feature:8:in `And I should see "Ресурсы Би-би-си"'
  
  Failing Scenarios:
  cucumber features/www.bbc.co.uk-russian/bidding.feature:4 # Scenario: Visiting home page

  It seems that problem is in webrat, temporary workaround for this is in : features/steps/http_steps.rb

  Then /^I should see "(.*)"$/ do |text|
     response.body.to_s.force_encoding('utf-8').should =~ /#{text}/m
  end

  but it's not good way
