title: Unescaped Characters in Cell Stop Row Processing PHPExcel
body: <p>This is a follow-on question from this one: <a href="https://stackoverflow.com/questions/8591808/algorithm-to-dynamically-merge-arrays">Algorithm to dynamically merge arrays</a></p>
  
  <p>There are unescaped characters in some of the cells in the spreadsheet. I try to escape them with addslashes() but phpexcel seems to ignore this and stop processing the rest of the rows. I get this error in the logs:</p>
  
  <pre><code> PHP Warning:  Unexpected character in input:  '\' (ASCII=92) state=1
  </code></pre>
  
  <p>I've looked through the API; I haven't seen any text formatting methods that I can use. (Please correct me if I'm wrong)</p>
  
  <p>Your help is appreciated.</p>
