title: Turkish characters not shown in html form placeholder
body: <p>In my form, i want to use a placeholder text for my textarea. It works fine except no turkish chars. </p>
  
  <pre><code>&lt;form action="http://localhost:8082/kaybeden/index.php/details/newcomment" method="post" accept-charset="utf-8" class="form-horizontal"&gt;
  &lt;div class="control-group"&gt;
    &lt;div class="controls"&gt;
      &lt;textarea name="comment_body" cols="150" rows="10" id="comment_body" placeholder="yazd���n yorum zeka bar�nd�rs�n." &gt;&lt;/textarea&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  &lt;div class="control-group"&gt;
    &lt;div class="controls"&gt;
      &lt;input type="submit" name="submit" value="Yolla" class="btn" /&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>"yazd���n yorum zeka bar�nd�rs�n" string is the output, normally it should be "yazdığın yorum zeka barındırsın.". My HTML charset is UTF-8. All the turkish chars are fine except  placeholder.</p>
