About this character

U+2131 (ℱ) is SCRIPT CAPITAL F, an uppercase letter in the Letterlike Symbols block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 1.1 (1993).

It is a font variant of U+0046 F (compatibility decomposition <font>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+0046 F. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.

It has standardized variation sequences that request a specific glyph shape: U+2131 U+FE00 — chancery style; U+2131 U+FE01 — roundhand style. See variation selectors.
