Headsup iOS keyboardage on ello!
" A heads up for iOS users: Don't use Emoji symbols from your iOS keyboard! They don't show up for other users. I've been seeing a lot of blank comments, because people are using an Apple emoji. For now, you have to use the "cross platform" emoji codes found here: http://www.emoji-cheat-sheet.com/
For desktop users, I put together a slightly more usable emoji cheat sheet here."
