title: What encodings does Buffer.toString() support?
body: <p>I'm writing an app in node.js, and see that I can do things like this:</p>
  
  <pre><code>var buf = new Buffer("Hello World!")
  console.log(buf.toString("hex"))
  console.log(buf.toString("utf8"))
  </code></pre>
  
  <p>And I know of 'ascii' as an encoding type (it'll take an ASCII code, such as <code>112</code> and turn it into a <code>p</code>), but what other types of encoding can I do?</p>
