U+FED9 "ﻙ" Arabic Letter Kaf Isolated Form Unicode Character

U+FED9 "ﻙ" Arabic Letter Kaf Isolated Form is a typographic variant of the Arabic letter Kaf, specifically designed to be used in isolation or at the end of a word when no connecting letters follow. It represents the same sound as the standard Kaf, corresponding to the English "k", but its distinctive curved, final form is one of four contextual shapes that the letter can take depending on its position in a word. This character belongs to the Arabic Presentation Forms-B block, which preserves the visual appearance of letters for digital text rendering and historical documentation, ensuring that the isolated form is displayed correctly in systems that require explicit encoding for each positional variant.
