title: Node.js / Express - How do I set response character encoding?
body: <p>Say I got:</p>
  
  <pre><code>app.get('/json', function(req, res) {
      res.set({
          'content-type': 'application/json'
      }).send('{"status": "0"}');
  });
  </code></pre>
  
  <p>I'm trying to send the response as UTF-8 with the following with no success:</p>
  
  <pre><code>app.get('/json', function(req, res) {
      // From Node.js Official Doc
      // http://nodejs.org/api/http.html#http_http_request_options_callback
      res.setEncoding('utf8');
  
      res.set({
          'content-type': 'application/json'
      }).send('{"status": "0"}');
  });
  </code></pre>
  
  <p>What is the correct way to set character encoding in Express?</p>
