title: How to convert large UTF-8 strings into ASCII?
body: <p>I need to convert large UTF-8 strings into ASCII. It should be reversible, and ideally a quick/lightweight algorithm.</p>
  
  <p>How can I do this? I need the <strong>source</strong> code (using loops) or the <strong>JavaScript</strong> code. (should not be dependent on any platform/framework/library) </p>
  
  <p><strong>Edit:</strong> I understand that the ASCII representation will not look correct and would be larger (in terms of bytes) than its UTF-8 counterpart, since its an encoded form of the UTF-8 original.</p>
