Where does come from?
The keycap digit 3 emoji has been around longer than you might expect. It made its debut as part of Unicode 3.0 in 1999 before joining Unicode’s Emoji 3.0 set in 2016, when it got its more emoji- and less glyph-y looking form. The emoji is made up of the digit three emoji and the combining enclosing keycap emoji.
On supported platforms, the keycap digit 3 emoji nearly universally renders as a white numeral 3 in a blue-gray square. The square is beveled on most platforms, appearing like a physical key on a keyboard with shadows, highlights, or an outline—hence keycap.
Who uses ?
It’s really just a fancy-looking, eye-grabbing three, keycap digit 3 is. Most often, the keycap digit 3 emoji is used to call special attention to the numeral 3 in some situation, such as a countdown to some important event or to highlight a major accomplishment.
