Mathematical Bold Italic Capital F 𝑭
Visual Description: The glyph is a capital F that looks bold and italic. It has a strong slant and thick strokes. It resembles a stylized Latin F made for math. In both print and digital math, it signals emphasis and a distinct mathematical meaning. It stands apart from regular letters.
Meaning & Usage: It is used to denote a specific variable, function, or operator in mathematical text. The bold italic style helps distinguish such symbols from ordinary letters. It can mark vectors, sets, or special quantities in equations and diagrams, guiding readers to treat F as a named object.
Historical Background: The idea of bold italic math symbols grew with printing and later digital typesetting. Designers created a family of math alphanumeric characters to keep variables readable and distinct. Unicode and font engines later standardized these styles, enabling consistent display across software, calculators, and learning tools without changing the symbol’s meaning.
Practical Use: In math work and educational apps, the bold italic F helps label special quantities and functions. It appears in formulas, proofs, and UI controls that compare values or toggle notations. Quick formatting tools or calculators may switch to bold italic symbols to emphasize or differentiate key objects in a workflow.

How to type / insert
Fast copy: click the Copy button near the top of this page.
By codepoint: in many editors and IDEs, you can insert via the Unicode code U+1D46D or a built‑in character picker.
HTML: use the numeric entity 푭 (hex) or 푭 (decimal) when an HTML entity is needed.
Compatibility & troubleshooting
Font support: if the symbol does not render, the current font likely lacks this codepoint. Choose a font with broad Unicode coverage or allow a fallback font.
Web pages: ensure your CSS font stack includes a general fallback; avoid relying on images for common symbols to preserve accessibility and copyability.
