What 𞹇 means
It is Arabic ḥāʾ used as a mathematical symbol.
The formula supplies its role; alone, it has no fixed value.
Arabic algebra moved from words to symbols: Ibn al-Banna and al-Qalasadi used algebraic notation in the 15th century, with evidence of use at least a century earlier. This form belongs to Arabic- and Persian-script mathematics.
Why not type ordinary ح?
Ordinary ح joins in text; 𞹇 is a separate math character.
Arabic letters change shape inside words; this mathematical form does not join.
