About this character

U+2115 (ℕ) is DOUBLE-STRUCK CAPITAL N, 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+004E N (compatibility decomposition <font>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+004E N. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.
