What 𝑨 means
It can mark a distinct variable. Math and physics often use bold italic capitals for matrices (number grids), but each author defines the notation.
A 1999 proposal documented these styles in scientific publishing, extending earlier math letters so plain text could preserve formula meaning.
NFKC reduces 𝑨 to plain A. It is Unicode’s compatibility text-normalization form.
Formal in equations; decorative in profiles.
Decorative use can disrupt search and screen-reader reading.
