U+FB91 "ﮑ" Arabic Letter Keheh Medial Form Unicode Character

U+FB91 "ﮑ" Arabic Letter Keheh Medial Form is a presentation form of the Arabic letter keheh (ﮐ), which itself represents the sound /k/ and is a variant of the standard Arabic letter kaf, commonly used in the Persian, Urdu, and other Arabic-script based languages. This specific medial form appears only when the letter is connected to both a preceding and a following character within a word, featuring a distinctive shape with a toothed, curved body and a horizontal connecting stroke on both sides. It belongs to the Arabic Presentation Forms-A block and is used primarily for text rendering and compatibility with older systems, as modern Unicode encoding prefers the standard Arabic letter kaf (U+06A9) for general text input.
