U+2611 ยท emoji since 2010
The ticked check box means done, selected, or confirmed on a list. It marks completed tasks and boxes happily ticked off.
It is the satisfying symbol of progress, the little square that says yes, handled, move on to the next thing.
In texting, โ๏ธ does not carry a widely used hidden or slang meaning, so you can usually take it at face value. People send it just as it looks, to add a little visual touch or set the mood of a message. Only a handful of emoji have a separate texting code, and โ๏ธ is not really one of them.
Its official Unicode name is the Check Box with Check emoji. In everyday chat most people just call it the check box with check emoji or describe what it shows. Copy and paste it from the button at the top of this page.
The โ๏ธ leads off a short phrase, and the rest of the words are written in cipher, every letter disguised as another emoji. Tap decipher to reveal the whole line.
Or make your own cipher in the translator.
