title: MIME base64 encode wide characters
body: <p>I use MIME::Base64 to encode some strings to safely pass over a URL 
  But there are time where the code breaks due to wide characters </p>
  
  <p>How can I safely encode wide characters, I need not use MIME::Base64 , any lightweight encoding will work for me </p>
  
  <pre><code>use MIME::Base64;
  print  MIME::Base64::encode_base64("\x{2019}s text");
  print "\nBye\n";
  </code></pre>
