title: How to convert a document into ASCII?
body: <p>So, for example you have a document: Ruby.txt, the contents of which are</p>
  
  <blockquote>
    <p>RuBYrUbYRuByByurBRyuRuby</p>
  </blockquote>
  
  <p>You for some reason need to convert the document's contents into ASCII code <strong>without</strong> printing it onto your screen (change the document's contents).
  How do you do that?</p>
  
  <p>P.S. Sorry, no code to debug</p>
