Mathematical Double-struck Small O Symbol Meaning
𝕠 (Unicode U+1D560, “MATHEMATICAL DOUBLE-STRUCK SMALL O”) is a mathematical symbol in the double-struck style. In practice, it appears in technical writing and typeset documents where authors want a distinct “O”-like character, often to represent a specific mathematical object, set, or variable in formal notation. Because it belongs to the Unicode Mathematical Double-Struck block, its appearance depends on your font’s support. When a font doesn’t support double-struck glyphs, the character may render differently or fall back to a plain substitute, so testing in your target environment is recommended.
Common uses
- •Typing mathematical variables in papers, worksheets, and presentations
- •Denoting a set or object with a distinct double-struck typographic style
- •Labeling elements in equation editors that support Unicode math symbols
- •Using in LaTeX-like or Unicode-based math text when supported by fonts
- •Designing math-themed UI text, icons, or educational content
