What 𝜛 means
It is math-italic varpi, the curled alternate form of Greek pi.
The unstyled Greek variant is ϖ. Mathematicians can use both pi forms as separate symbols in one document; the equation gives 𝜛 its particular role.
How do I type varpi?
In Unicode-math, use \mitvarpi for this character.
The standard LaTeX command \varpi produces the underlying Greek variant ϖ; it gives that curled form without explicitly naming this math-italic Unicode character.
Why does the italic style matter?
Math typography can use style to distinguish variables.
Unicode's separate mathematical alphabets preserve those distinctions in plain text, so italic style can carry meaning rather than decoration.
The character encoding specifies a semantic style, not one fixed drawing; its curl may vary slightly among math fonts.

1Why does 𝜛 turn into ϖ?
It can. NFKC, a Unicode text-normalization form, folds mathematical alphabets to their base Greek forms, so 𝜛 becomes ϖ. Keep the original when its explicit math-italic style matters.
