What 𝟫 means
It is nine in a sans-serif mathematical style. Mathematical notation uses type styles to distinguish symbols, so this math 9 can preserve its form in plain text. Unicode's mathematical alphabets expanded an older, smaller set of math-style letter symbols into a broader group of letters and digits.
The formula supplies the specific role; sans-serif by itself does not assign this digit a new mathematical value.
Unicode intends this mathematical form for notation; in ordinary prose, style a regular 9 with the font.
NFKC/NFKD can turn it into plain 9.

Questions people ask
2Why can 𝟫 lose its sans-serif look in a formula?
A MathML renderer may ignore the style if suitable font support is unavailable; the character in the text remains 𝟫.
Can normalization change 𝟫 to 9?
Yes. NFKC and NFKD compatibility normalization fold this mathematical form to plain 9; NFC and NFD preserve the distinction.
