title: HTML content encoded, started with '&#' sign
body: <p>I have received an email and the body is formed in HTML format. However, I was wondering how can I decode the encoded content as following:</p>
  
  <p><code>&lt;a href=3Dhttp://&amp;#65296;&amp;#65294;&amp;#65351;&amp;#65351;&amp;#47;&amp;#68;&amp;#70;&amp;#116;&amp;#50;&amp;#85;&gt;</code></p>
  
  <p>Could anyone tell me how to decode the string? The transfer encoding is Qouted-printable, and the charset is big5. However, I tried to decode the content with qp-decoder and nothing works. Thanks.</p>
