#### Unsupported emojis fallback
Certain sets dont support all emojis (i.e. Messenger & Facebook dont support `:shrug:`). By default the Emoji component will not render anything so that the emojis dont take space in the picker when not available. When using the standalone Emoji component, you can however render anything you want by providing the `fallback` props.

#### Using with `dangerouslySetInnerHTML`
The Emoji component being a [functional component](https://medium.com/missive-app/45-faster-react-functional-components-now-3509a668e69f), you can call it as you would call any function instead of using JSX. Make sure you pass `html: true` for it to return an HTML string.
```js
<span dangerouslySetInnerHTML={{
__html: Emoji({
html: true
set: 'apple'
emoji: '+1'
size: 24
})
}}></span>
```
## Custom emojis
You can provide custom emojis which will show up in their own category.
