Mathematical Sans-serif Small F Symbol

𝖿 is a Unicode mathematical letter: mathematical sans-serif small f (U+1D5BF).

U+1D5BF

𝖿 is a Unicode character from the Mathematical Sans-Serif block. It’s commonly used like a variable symbol in math, notes, and technical layouts where sans-serif math styling is desired. You can copy it directly or use its HTML/CSS/JavaScript escapes.

Mathematical Sans-serif Small F Symbol Meaning

The character 𝖿 is “MATHEMATICAL SANS-SERIF SMALL F” with Unicode code point U+1D5BF (HTML entity: 𝖿). In practice, it’s used as a stylized lowercase letter “f” in mathematical text. Designers and technical writers use it when they want the look of a sans-serif math variable rather than a standard italic “f” or a regular text “f”. Like other math alphanumerics, it typically represents a variable, function name, or label—exact meaning depends on the surrounding notation in the document.

Common uses

  • Labeling mathematical variables or function symbols in sans-serif math text
  • Writing technical documentation where consistent math letter styling improves readability
  • Designing equations in slide decks or design tools that support Unicode math characters
  • Using it in typography mockups or UI prototypes that require a math-styled “f” glyph
  • Creating consistent notation in STEM notes, blogs, or posts that use Unicode symbols
