title: Regex how to replace \r\n with an actual newline in string
body: <p>Because \r\n are "special" chars in a regex I have a problem identifying what I actually need to put in my expression. </p>
  
  <p>basically i have a string that looks something like ... </p>
  
  <pre><code>bla\r\nbla\r\nbla
  </code></pre>
  
  <p>.. and i'm looking to change it to ...</p>
  
  <pre><code>bla
  bla  
  bla
  </code></pre>
  
  <p>... using a regular expression.</p>
  
  <p>Any ideas?</p>
