title: What is the purpose of the cef.pak file in cefsharp?
body: <p>In the <a href="https://github.com/cefsharp/CefSharp/wiki/Frequently-asked-questions#Runtime_dependencies" rel="noreferrer">FAQs of CefSharp</a>, it states that you should disable Package Loading:</p>
  
  <pre><code>var settings = new CefSharp.CefSettings 
  {
      PackLoadingDisabled = true
  };
  </code></pre>
  
  <blockquote>
    <p>which is normally OK for a production-mode application</p>
  </blockquote>
  
  <p>I have an issue where on a particular website a red border is appearing around a drop-down box.  If I set <code>PackLoadingDisabled = false</code> and ensure that the <code>cef.pak</code> file is in the folder (This cef.pak is distributed with the CefSharp nuget package.  I am <em>not</em> including any other .pak file except locates/en-US.pak) then this fixes the issue.</p>
  
  <p>My question is, <strong>What purpose does this cef.pak file serve?</strong></p>
  
  <p>I've looked at the <a href="https://chromiumembedded.googlecode.com/svn-history/r608/trunk/cef3/tools/distrib/mac/README.txt" rel="noreferrer">CEF3 Readme</a> and it shows that it is optional, but it isn't very clear on what purpose this Pack serves.  Before I go and include it in my software distribution I need to know exactly what it is for.</p>
  
  <p><strong>Am I safe to enabled Pack Loading in my release version?</strong></p>
