title: What is a cross platform regex for removal of line breaks?
body: <p>I am sure this has been asked before, but I cannot find it.</p>
  
  <p>Basically, assuming you are parsing a text file of unknown origin and want to replace line breaks with some other delimiter, is this the best regex, or is there another?</p>
  
  <p><code>(\r\n)|(\n)|(\r)</code></p>
