U25CB

U25CB (more commonly written U+25CB) is the Unicode code point for the character named "WHITE CIRCLE" (○). It belongs to the Geometric Shapes block and is rendered as an unfilled circular glyph whose exact weight and diameter depend on the font and rendering environment.

The white circle is used typographically and graphically as a bullet, marker, radio-button indicator for an unselected option, diagram node, or map symbol. It also appears in lists, forms, and user-interface mockups where an empty circular shape is required. Because it is a generic geometric symbol, its semantics are context-dependent rather than carrying inherent semantic content.

In Unicode and web contexts it can be referenced as U+25CB, or in HTML as ○ or ○. Visual appearance varies between fonts and platforms; some implementations render a very thin outline while others show a thicker ring or a larger overall size.

There are several visually related characters, including U+25CF BLACK CIRCLE (●), U+25EF LARGE CIRCLE (◯), U+26AA MEDIUM WHITE CIRCLE (⚪), U+26AB MEDIUM BLACK CIRCLE (⚫), and U+2218 RING OPERATOR (∘), which differ in weight, size, or mathematical meaning. Careful selection among these code points is recommended when specific visual or semantic properties are required.
