title: Puppeteer failed to render emojis when running in Ubuntu
body: <p>I have a script that uses puppeteer to take screenshot of DOM components and outputs an image. Everything works fine on MacOS but when I run this on Ubuntu the emojis become a rectangle. Does anyone know why is this happening?</p>

  <li>MacOS: (where you can see a rocket emoji)</li>
  </ul>

  <li>Ubuntu: (emoji becomes a rectangle)</li>
