title: Smarty includes : strange empty characters
body: <p>I'm experiencing strange white space when loading Smarty templates in a Prestashop installation. It happened without me noticing it so I can't trace it back to a specific change. </p>
  
  <p>It seems to happen just before the include and generates some empty space in the browser.</p>

  <p>Here is a sample of the HTML where this whitespace occurs: </p>
  
  <p><a href="http://twi.tl/051i3o0T062F1X2L3u3k" rel="nofollow noreferrer">http://twi.tl/051i3o0T062F1X2L3u3k</a></p>
  
  <p>Moving your cursor in the file you will notice the blank character just after the #main div and somewhere before the #customization div.</p>
  
  <p>Looking in forums, some posts talk about the Byte Order Mark being outputted. </p>
  
  <p>Aside from moving a comment through every line of Prestashop to try to find a needle in a haystack, is there perhaps a more intelligent approach to finding the rogue characters. Perhaps a function which allows me to pinpoint at what line of what file that line of the output is generated. </p>
  
  <p>Thank you</p>
  
  <p>An yes I will install an SVN</p>
