title: How to convert data to utf-8 in node.js?
body: <p>I am using node.js with express. I read out data from MongoDB with Mongoose and deliver it the normal way with <code>res.send(data)</code>. Unfortunately the delivering fails for some requests. Even so the header says the encoding is utf-8, it seems to be ANSI in some cases, causing the jsonp callback function to fail with an error.</p>
  
  <p>You can reproduce the error at this page: <a href="http://like-my-style.com/#!single/9837034">http://like-my-style.com/#!single/9837034</a> . The jsonp call fails just on some products, most of them (also the ones with special chars) work fine.</p>
  
  <p>How can I ensure, that a given String is encoded in utf-8 in node.js?</p>
