title: Convert from UTF-8 to Shift-JIS
body: <p>The current email is in UTF-8. It's not working on Shift-JIS. <br>
  How can I convert from UTF-8 to SHIFT-JIS. The solution needs to be a PHP solution.</p>
  
  <p>This is what I have tried so far</p>
  
  <pre><code>$subject = mb_convert_encoding ($subject, "JIS", "SJIS");
  
  $subject = base64_encode ($subject);
  
  $subject = "=?iso-2022-jp?B?" . $subject . "?=";    
  </code></pre>
