title: Conversion of buffer data to blob in NodeJS
body: <p>I get Buffer Data from a storage like <code>&lt;Buffer 48 65 79 20 74 68 65 72 65 21&gt;</code> for instance. I needed to convert it into a blob. But when i tried doing a toString() to get encoded text just like how a browser would render an attachment , i get all texts as unicode characters. I am in need of a blob I can send to UI along with other params in JSON , which could be used for view using HTML5 FileReader API. Could you please favour. </p>
  
  <p>What i tried was below, where buffer refers to the data as in first line. </p>
  
  <pre><code>let binBuffer = Buffer.from(buffer,'binary').toString('utf8');
  </code></pre>
