Black Square For Stop (⏹) is encoded as U+23F9 and has the formal Unicode name BLACK SQUARE FOR STOP. Unicode classifies it as Symbol, Other in the Miscellaneous Technical block. Its name places it in the emoji pictograph family, which gives the page a narrower identity than the glyph alone. The code point is the stable identifier when fonts, copy-and-paste, or surrounding context make the glyph ambiguous.

The Same Unicode Identity Can Have Different Artwork

Unicode defines the encoded identity U+23F9, while the visible shape is produced by a font, emoji set, and shaping engine. Emoji platforms can redraw the same encoded character or sequence with different artwork, proportions, and color.

For identification, compare code points and sequence structure rather than expecting pixel-for-pixel consistency. Rendering can change while the underlying Unicode record stays the same.

For a different unknown mark, try what symbol is ⏹? and identify the character from its glyph, Unicode value, or appearance.

Code-Point and UTF-8 Forms for ⏹
