title: Encoding error of watching sass files with gruntfiles and phpstorm
body: <p>I'm using PhpStorm and a gruntfile.js to compile and watch my <code>.scss</code> files.</p>
  
  <p>When I use the PhpStorm terminal to watch sass with <code>grunt watch</code> I get the error 
  <code>(Line 70: Invalid US-ASCII character "\xC3")</code> for <code>//ééé</code>.</p>
  
  <p>But when I use the Mac terminal to watch sass with <code>grunt watch</code> it's working well.</p>
  
  <p>All files are in UTF-8 and I updated sass/compass to the last version.</p>
  
  <p>I don't know how to solve this problem. I didn't find terminal encoding setting in PhpStorm.</p>
