What 𞹪 means
It is Arabic kaf in a distinct mathematical style. In an equation, it can label a variable, and the surrounding formula tells you what it represents. Arabic mathematics uses several visually distinct letter styles that can carry meaning, so this form is a separate character rather than ordinary kaf stretched by a font.
Arabic-letter algebra is documented from the 12th century in the work of Ibn al-Yasamin, a mathematician from Muslim-ruled Iberia. A copy made in the 18th century in Jerba, Tunisia, shows a developed North African (Maghrebi) symbol system in its margins. These manuscripts record the wider history of Arabic algebra; 𞹪 is one specific mathematical letter style.
A specialized letter style for Arabic-script equations.
Ordinary Arabic text uses ك; this character is its distinct stretched mathematical form.

Questions people ask
1Why does 𞹪 sometimes become ك?
Yes—Unicode's NFKC normalization can fold 𞹪 to ordinary ك. NFKC is a text-normalization form that applies compatibility mappings; this character's mapping removes the stretched mathematical style. NFC does not apply that compatibility mapping.
