Where does come from?
The circled ideograph congratulation emoji, as it’s officially called, is a bright red button with a white Japanese kanji character that translates to “congratulations” in Japanese—and in the Chinese character from which it is derived. The character is also often translated as blessings, widening its use to expressions of gratitude.
Commonly called the Japanese “congratulations” button, the emoji was first released under Unicode 1.1 in 1993 and has been included in all subsequent updates, notably Unicode 6.0 in 2010, which introduced emoji to many Westerners for the first time.
Its appearance is fairly uniform across platforms, except for the vendor LG, which features a black character on a yellow button.
Who uses ?
Though written in Japanese, the circled ideograph congratulation emoji is often used for congratulatory and celebratory messages in English contexts, too. Since it generally conveys excitement, goodwill, and thankfulness, the emoji is commonly found in birthday wishes and holiday greetings (e.g., Happy New Year! ㊗️).
Because it often observes a special day or occasion, the circled ideograph congratulation sometimes substitutes for the word happy in the construction Happy X!, (e.g., ㊗️ Halloween!).
The circled ideograph congratulation emoji is occasionally used simply for its bright red color or its Japanese character, regardless of its specific meaning. Users who include the emoji in these situations are aiming for a visual effect, and therefore may not intend “congratulations.”
This emoji also appears on merchandise, especially clothing items.
