About this character

U+1D4BF (𝒿) is MATHEMATICAL SCRIPT SMALL J, a lowercase letter in the Mathematical Alphanumeric Symbols block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 3.1 (2001).

It is a font variant of U+006A j (compatibility decomposition <font>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+006A j. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.
