What ⚫ means
Unicode's 2008 math guide lists ⚫ among size-graded circles for notation. A 2011 Unicode proposal noted that Wingdings, a Microsoft symbol font, used this dot both as a shape and as a recording control. Unicode still notes ⚫ as a record-function symbol, but that overlap led to a dedicated record symbol, ⏺, which is the clearer choice for a button.
Don't confuse it with
3⚪•🔴
White Circle
The white circle, hollow or pale. Swap them and a checklist or color tag reads backwards.
Bullet
The small text bullet. Same job in a list, but it stays plain punctuation and never shows as emoji art.
Red Circle
The red circle, the familiar live or recording signal in apps and posts; black reads as a neutral marker in chat.
Worth knowing
- The characters behind ⚫ existed in Unicode 5 years before anyone was allowed to draw them in colour: Unicode 4.1 in 2005, emoji presentation in 2010.
- ⚫ is a single code point, so it survives copying through almost anything — old databases, SMS gateways, printer drivers.
