title: wkhtmltopdf amazon linux won't encode emoji
body: <p>I'm trying to generate a PDF via <code>wkhtmltopdf</code> in an <code>Amazon Linux</code> os, everything works fine, but when i try to use emoji on the <code>HTML</code>, the fonts break and the emoji is displayed as a black box.
  Before deploying, i tried locally and it works, locally i have <code>Ubuntu</code>, so my guess is that i'm missing something (fonts?) in the production (the amazon linux instance) server. I tried to install <code>Google Noto</code> font but nothing happened. I'll attach 2 screens of the same <code>HTML</code> page, generated by the same command via <code>wkhtmltopdf</code>:</p>
  <p>Local (Ubuntu):
  <a href="https://i.stack.imgur.com/1q2zI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1q2zI.png" alt="Local Image" /></a></p>
  <p>Production (Amazon Linux):
  <a href="https://i.stack.imgur.com/d66Cy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/d66Cy.png" alt="Production Image" /></a></p>
  <p>As you can see, even the font below the broken emoji is not rendered as aspected, i'll add the command i use in both servers:</p>
  <p><code>/my/path/to/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64 --lowquality 'file:///my/path/to/page-test-pdf.html' '/home/user/test.pdf'</code></p>
  <p>Thanks for your time.</p>
