title: weird ! and space character while sending mail
body: <p>So here is my situation : On a godaddy server, I've got a php script which sends periodically html emails (a kind of newsletters). And for a reason I can't explain, in some of the emails I send (always at the same exact spot), a ! character appear, along with an unusual space. Here are some example : </p>
  
  <ul>
  <li>"I am ! so certa in" instead of "I am so certain" </li>
  <li>"that anger ! at them" instead of "that anger at them"</li>
  <li>"to be childre! n during" instead of "to be children during"</li>
  </ul>
  
  <p>Some more details regarding the script's mechanics : it reads the content email from .html files (converted from a .doc file - I know that's a wierd idea, and the html code generated is shitty, the formatting aim to resolve this issue), does some formatting, and sends it with the appropriate headers. What I did try to diagnose the issue : </p>
  
  <ul>
  <li>Tried to view the email with different software (from my gmail account, my old Windows live mail account and outlook). It's all the same.</li>
  <li>Tried to change the charset of the email (from utf-8 to ISO-8859-1).</li>
  <li>Made sure there was not any rogue character by using the html_entity_decode function.</li>
  <li>Checked if the file on the server didn't get deformed for some random reason - and it's note.</li>
  </ul>
  
  <p>So any idea about this?</p>
