Emojis can be used to make push messages more 'eye-catching' and increase user interaction with your content.
In order to include emojis in a push notification, you need only to call an emoji keyboard shortcut on your computer and choose the appropriate emoji (e.g. 'Command + Control + Space' on the Mac).
Emojis can be added to the title, description, and additional buttons. In order to add emojis to push notifications of the dynamic content type, find the universal Unicode value for the necessary emoji (e.g. ❤️) and add it to the appropriate tag in the RSS feed.
