Rails.root string conversion gives an ASCII string on Ruby 1.9.2

#6430

Here is a failing test file on Rails 3.0.3

#encoding: UTF-8
require 'test_helper'

class RootTest < ActionDispatch::IntegrationTest
  fixtures :all

  # Replace this with your real tests.
  test "Rails.root encoding is UTF-8" do
    assert_equal "UTF-8", "#{Rails.root}".encoding.name
  end

  test "Dummy encoding is UTF-8" do
    assert_equal "UTF-8", "#{"toto"}".encoding.name
  end
end

This is not a Rails thing.
Try the following
```
➜  cat santiago.rb 
module Santiago
  def name
    'Santiago'
  end
end
➜  /tmp  cat app.rb
#encoding: UTF-8

require 'santiago'

puts "#{Santiago.name}".encoding.name
➜  /tmp  ruby -I. test2.rb
"US-ASCII"
```
Ruby encodes the string to match the magic comment when you define literal strings
