I've noticed that emoji use isn't built into the steemit editor 😦
You can still add emojis to your posts by cutting and pasting from: GetEmoji 🤘🤘
Resteem and Upvote this post and maybe before Steemit leaves beta they will notice they really need emoji support and add it.
We need our emojis‼️
Look at this post to see if it provides the emojis you seek:
https://steemit.com/steemitguide/@steemitguide/steemitguide-tutorial-on-how-to-use-unicode-characters-on-steemit-includes-cheatsheet-on-smileys-icons-and-symbols-which-are
they have emojis over on steemit.chat so they could probably easily add it here.
Would be cool
