title: Send message in hindi language using mg91 api in node.js
body: <p>I am using msg91 Node.js API to send SMS. It is working fine if the message's text is in English.
  Now I want to send SMS in Hindi.</p>
  
  <p>Problem is, if I don't encode the message, it returns <code>Authentication error</code>.  Post encoding it says the message is sent, but I don't receive any message on the test target.</p>
  
  <p>Error Message:</p>
  
  <pre><code>{ success: 'false',
    token: 'Authentication failure' }
  </code></pre>
  
  <p>Sample message is: </p>
  
  <blockquote>
    <p>मोजो में आपका स्वागत है</p>
  </blockquote>
  
  <p>npm module used: msg91 </p>
  
  <pre><code>npm install --save msg91
  </code></pre>
