When to use it
◼ writes U+25FC (Black Medium Square), a maths symbol from the Unicode Geometric Shapes block, encoded since Unicode 3.2. For more than a symbol or two, MathML, supported in all major browsers since 2023, gives proper maths spacing and layout.
The name comes from the HTML5 list (much of it shared with MathML), so it works in every current browser but not in XML or XHTML served as XML, where the numeric reference is the safe choice.
This character also has an emoji form: ◼️ Black Medium Square. Add U+FE0F after it for the emoji style or U+FE0E for the text style.
