Mathematical Fraktur Small F 𝔣
Visual Description: The symbol looks like a stylized f with decorative lines. It has a tall stem and a curved bowl, shown in Fraktur styling. The design keeps a legible form even in small print. In formulas, it reads like a distinctive variable. In editors, it stays clear at mixed sizes. UI previews show the Fraktur look clearly.
Meaning & Usage: It is often used as a variable or as a function name in math and logic. The Fraktur style signals a special set or a differing role from plain letters. In quick calculators, the symbol marks a parameter or a placeholder. Some editors offer a Fraktur button or hotkey. This helps quick comparisons.
Historical Background: Fraktur styling comes from typographic traditions that used ornate letters in print. The small f variant appears in many mathematical fonts as a way to signal a special idea. In digital work, fonts map the style to the same letter, keeping the math consistent and readable.
Practical Use: In notes and software, you can apply Fraktur to a symbol by selecting it and choosing a font style. In calculators, notebooks, and editors, the mark helps separate types of variables or constants. Quick UI controls may include a style toggle, a color cue, or a symbol palette. Use it for clarity.

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+1D523 or a built‑in character picker.
HTML: use the numeric entity 픣 (hex) or 픣 (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.
