title: How to set charset="utf-8" in the javascript file itself
body: <p>I am trying to set charset="utf-8" inside the javascript file itself, not in the script tag,
  I know that I can do this:</p>
  
  <pre><code>&lt;script type="text/javascript" charset="UTF-8" src="xyz.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>But unfortunately, this solution needs me to do the same step with hundreds of websites which are using the same script. so I am trying to set the charset in the javascript file itself. 
  Is this possible?</p>
  
  <p>thanks</p>
