U25A0

U+25A0 is the Unicode code point for BLACK SQUARE, a solid square symbol. It belongs to the Geometric Shapes block (U+25A0–U+25FF) and is categorized as a symbol of the “Other” type. The glyph is a filled square and is used as a simple geometric glyph in text and graphics.

The character is encoded in UTF-8 as E2 96 A0 and can be represented in HTML with numeric references such as ■ or ■. Its visual appearance depends on the font and rendering system in use; some fonts render a crisp, uniform square, while others may vary in edge sharpness or size.

Common uses of U+25A0 include typography and document design where a basic geometric shape is needed. It is also used in user interfaces as a simple square icon or as a checkbox-like element in certain designs. It is not an emoji, and its appearance is generally not standardized as an emoji glyph across platforms.

Related square characters include U+25A1 WHITE SQUARE, a hollow square, and U+25A2 BLACK SMALL SQUARE, a smaller filled square. These characters form part of the same geometric shapes set and are used for similar purposes where a square glyph is required.
