U+25AA BLACK SMALL SQUARE: ▪ – Unicode

U+25AA was added in Unicode version 1.1 in 1993. It belongs to the block U+25A0 to U+25FF Geometric Shapes in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as square bullet.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+25AA forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

The CLDR project calls this character “black small square” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: black, geometric, small, square.

This character is designated as an emoji. It will be rendered as monochrome character on conforming platforms. To enable colorful emoji display, you can combine it with Variation Selector-16: ▪️ See the Emojipedia for more details on this character’s emoji properties.

The Wikipedia has the following information about this codepoint:

In Euclidean geometry, a square is a regular quadrilateral, which means that it has four straight sides of equal length and four equal angles (90-degree angles, π/2 radian angles, or right angles). It can also be defined as a rectangle with two equal-length adjacent sides. It is the only regular polygon whose internal angle, central angle, and external angle are all equal (90°), and whose diagonals are all equal in length. A square with vertices ABCD would be denoted $◻$ ABCD.
