- **unicode** - If you set this option to true, the filter will generate something like this:
```html
<span class="github-emoji" title=":sparkles:" data-src="https://assets-cdn.github.com/images/icons/emoji/unicode/2728.png">&#x2728;</span>
```
Then you can fallback to image with JavaScript. For example, with jQuery:
```javascript
$('span.github-emoji').each(function (i, emoji) {
var $emoji = $(emoji)
var codepoint = $emoji.html()
$('<img height="20" width="20">')
.prop('src', $emoji.data('src'))
.prop('alt', $emoji.attr('title'))
.on('error', function () {
// image loading failed
$emoji.html(codepoint)
})
.appendTo($emoji.empty())
})
```
