What 𝓃 means
It marks a distinct math variable; the formula supplies its value.
“Script” names this calligraphic style for mathematical letters. By 1999, Unicode proposed completing earlier isolated letter-shaped symbols into full alphabets, so plain text could preserve styles already used in scientific publishing.
Can NFKC turn 𝓃 into n?
Yes: normalization can fold it to plain n.
NFKC and NFKD are text-cleanup modes called compatibility normalization; they fold math styles to ordinary letters. Avoid them when 𝓃 must stay distinct from n.
