What 𞹶 means
It is ث (thāʾ) in a distinct mathematical style.
Arabic-script math uses letter styles as part of its notation: the stretched form can distinguish one symbol from another, rather than just decorate a font. Such styles were used for centuries in manuscripts and traditional print. A 2006 Unicode proposal documented stretched forms in Arabic mathematical handbooks and sought to preserve those distinctions in digital text. The same style system is used in Persian mathematics, which also uses an Arabic-based script. Unlike ordinary Arabic letters, these mathematical symbols do not change shape to join neighboring letters.
Specialist and neutral; it belongs in Arabic-script mathematical notation.
Don't substitute ordinary ث; the stretched style can distinguish mathematical symbols.

1Can normalization turn stretched theh into ordinary ث?
Yes. Unicode compatibility normalization (NFKC) maps it to ordinary ث, removing the stretched-style distinction; check mathematical text if a system normalizes it.
