title: Javascript code in Chrome extension with wrong charset encoding?
body: <p>I'm fighting with some literal strings in my JS file.<br>
  When I edit them in my IDE I can see chars like "ó" without problem, the file is UTF-8, but when I test in the chrome extension the JS code from Chrome Dev Tools is showing weird chars like "Ã³" (in the code!).<br>
  And this was not happening before, I'm a bit lost about what could be causing this, any clue?    </p>
  
  <p><strong>EDIT:</strong>
  OK, I fixed it by adding charset="utf-8" to the script tag, but I'm curious about why is this happening, because I was using the same JS file without problem many times before on the same extension.  </p>
