title: mobileOK W3C validation/ CSS / The resource does not specify UTF-8 as character encoding
body: <p>I try to validate my according to w3c <a href="http://validator.w3.org/mobile" rel="nofollow">mobileOK validation tool</a><br>
  The validation gives me a warning:
  The resource does not specify UTF-8 as character encoding</p>
  
  <p>WHy?:
  One of the resources required to render the page (most likely a CSS style sheet) does not declare its encoding as UTF-8 in
  an HTTP Content-Type header. Check that its content is properly encoded, and consider declaring its encoding at the HTTP level.</p>
  
  <p>The validation tool point out my css file.</p>
  
  <p>At the begining of my css, I have a correct " @charset "UTF-8";" </p>
  
  <p>I have checked this site: <a href="http://www.w3.org/International/questions/qa-css-charset.en.php" rel="nofollow">http://www.w3.org/International/questions/qa-css-charset.en.php</a></p>
  
  <p>And it says that I can also declare the encoding of the file in the HTTP Content-Type header with something like: </p>
  
  <p>Content-Type: text/css; charset=UTF-8 </p>
  
  <p>I have already a comparable declaration in my html page ( &lt; meta http-equiv="Content-type" content="text/html;charset=UTF-8" / > )</p>
  
  <p>But I have no clue how to use this "Content-Type: text/css; charset=UTF-8" declaration for my css... shall I put it in css or html ? how ?</p>
