This is a tool to convert Emoji Unicode codepoints into the human-friendly codes used by http://www.emoji-cheat-sheet.com/ and back again.

By doing this, you can ensure that users across devices can see the author’s intention. You can always show users an image, but you can’t show them a range of characters their system does not support.
This gem is primarily for handling emoji characters in user-generated content. Depending on your technical stack, these characters could end up being lost.
Rumoji.encode(str)
# Takes a String, transforms Emoji into cheat-sheet codes
Rumoji.decode(str)
# Does the reverse
Rumoji.encode_io(read, write)
# For an IO pipe (a read stream, and a write stream), transform Emoji from the
# read end, and write the cheat-sheet codes on the write end.
Rumoji.decode_io(read, write)
# Same thing but in reverse!
gem install rumoji
Note that rumoji has only been tested in Rubies >= 1.9!!!
puts Rumoji.encode("Lack of cross-device emoji support makes me 😭")
#=> Lack of cross-device emoji support makes me :sob:
Here's a fun file:
Rumoji.decode_io($stdin, $stdout)
On the command line
echo "But Rumoji makes encoding issues a :joy:" | ruby ./funfile.rb
#=> But Rumoji makes encoding issues a 😂
Implement the emoji codes from emoji-cheat-sheet.com using a tool like gemoji along with Rumoji, and you'll easily be able to transform user input with raw emoji unicode into images you can show to all users.
Having trouble discerning what's happening in this README? You might be on a device with NO emoji support! All the more reason to use Rumoji. Transcode the raw unicode into something users can understand across devices!
Thanks!
