title: Apktool/aapt/aapt2 error parsing unicode characters in xml files
body: <p>I am trying to use apktool/aapt/aapt2 to rebuild an APK but I encountered an error when using the tools. The message states "error: not well-formed (invalid token)". This is because of the use of unicode characters in the various xml files for the class names etc.</p>
  
  <p>Is there anyway I can convert those unicode names to an ASCII equivalent? I have tried to escape the characters in the XML files using</p>
  
  <ul>
  <li>&amp;#x....</li>
  <li>&amp;#.... (decimal equivalent of &amp;#x)</li>
  <li>\u....</li>
  <li>\xxxx</li>
  </ul>
  
  <p>However, none of the above escaping works. Any advice is greatly appreciated.</p>
