White Circle With Lower Right Quadrant

At code point U+25F6, the white circle with lower right quadrant (◶) occupies a carefully chosen position within the Geometric Shapes allocation. The Unicode Consortium assigned this character to address the need for a reliable, cross-platform representation of this symbol in electronic documents and interfaces.

The hexadecimal value 25F6 places this character at decimal position 9718 in the Unicode table. This position within the Geometric Shapes range means it shares encoding characteristics with its neighboring characters. The CSS notation \25F6 is particularly useful in pseudo-element content properties, while \u{25F6} works in template literals and string concatenation.

Known by its descriptive name referencing "white circle," this character serves a specific role that generic symbols cannot fill. It appears in specialized typography, technical standards, and digital content where precision in symbol choice directly affects meaning or layout.

Geometric shape characters bring the clarity of pure form into text. Circles, squares, triangles, diamonds, and their filled or outlined variants serve as versatile building blocks for data visualization, UI indicators, bullet points, and decorative elements. The extended block adds stars, crosses, and polygons that support everything from rating displays to complex diagramming within plain text environments.

Geometric symbols have appeared in printed text for centuries — printers used small squares and circles as paragraph markers and section dividers long before digital typography. The original Unicode 1.0 Geometric Shapes block codified the most common forms, drawing from existing character sets like ISO 8859 and various national standards. Unicode 7.0 introduced Geometric Shapes Extended, adding filled and outlined variants in multiple sizes, responding to demand from emoji designers and UI toolkit developers who needed these shapes as composable elements.
