I've had a problem where I was trying to display an Emoji in a Chrome Extension header of default popup HTML, page_action.html (specified by page_action -> default_popup in manifest.json).

But got the jumbled up characters instead.

Emoji displayed as gobbledygook

The problem was that I had to instruct Chrome that I am using a unicode by adding a charset meta tag.

      
        <html>
      
          <head>
      
            <meta charset="UTF-8" />
      
            ...
      
          </head>
      
        ...
      
        </html>

Character Set set to UTF-8

This has fixed the issue and shows the cute 🐥 emoji correctly in the Chrome Extension popup.

You can now see the cute baby chick 🐥
