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>
view raw meta.html hosted with ❤ by GitHub
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 🐥
