About this character

U+1D417 (𝐗) is MATHEMATICAL BOLD CAPITAL X, an uppercase 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+0058 X (compatibility decomposition <font>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+0058 X. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.
