body: <p>I want to display first character of user in django templates.
  I want to make a image of user first character like caption or avatar</p>
  
  <p>like this <a href="https://meta.discourse.org/t/switch-from-gravatar-to-html-css-letters-for-no-avatar-users/15336" rel="noreferrer">https://meta.discourse.org/t/switch-from-gravatar-to-html-css-letters-for-no-avatar-users/15336</a></p>
  
  <pre><code>&lt;p&gt;{{postone.user}}&lt;/p&gt;
  </code></pre>
  
  <p>so i will get result like any name "Gaurav" or "Amit" but i just want first letter of them like "G" or "A"
  So i can display it like image of first letter.</p>
