Emojis can be pasted into the message content field from an external source
This Wikipedia page includes a full table of emojis that can be copied and pasted into the messaging portal - just hover over the emoji you want to use, then right-click and select "copy."
Things to note:
- Sending emojis depends on the recipient network's ability to support them.
- If the recipient network doesn't support emojis, they will be stripped out.
- Emojis are counted as 2 unicode characters each (please note that using Emoji changes the encoding of the message to Unicode).
