U+FB01 "fi" Latin Small Ligature Fi Unicode Character
Unicode Version 17.0
fi
U+FB01 "fi" Latin Small Ligature Fi is a typographic ligature that combines the letters f and i into a single glyph, historically used in printing to improve readability and aesthetic flow by merging the overhang of the f with the dot of the i. It is part of the Latin Extended Additional block, and while it preserves the visual appearance of a traditional ligature, its use in modern digital text is often discouraged in favor of the separate characters f and i, as relying on such precomposed forms can complicate searching, sorting, and accessibility. This character is distinct from the alphabetic combination "fi" in encoded form, though it typically renders identically when a font supports automatic ligatures.
