'Then the file "myfolder/myfile.txt" should contain' escaping contents

Following the gem development guide, I have come to the part where I am checking the contents of a file. Because there are pounds and multiple lines, the contents being checked is escaped with \# and \n.

  Scenario: Recipes                                  # features/generator.feature:6
    When I run `foodie recipe dinner steak`          # aruba-0.5.3/lib/aruba/cucumber.rb:60
    Then the following files should exist:           # aruba-0.5.3/lib/aruba/cucumber.rb:256
      | dinner/steak.txt |
    Then the file "dinner/steak.txt" should contain: # aruba-0.5.3/lib/aruba/cucumber.rb:300

Is there something that I am doing wrong, or is this guide older and there should be something else that I should do to prevent the file from checking against escaped text?

Update:

If I change the file and the test to one line and remove the pound characters, the test will pass.

Escaping is not your problem, you have a typo in your generator:

#### Indtructions ####

Pounds in expected part are escaped because it is a regular expression. got part is a string.
