U+FEDB "ﻛ" Arabic Letter Kaf Initial Form Unicode Character

Unicode Version 17.0

U+FEDB "ﻛ" Arabic Letter Kaf Initial Form is a presentation form of the Arabic letter Kaf, specifically designed to appear at the beginning of a word within a cursive text context, where it connects to the following character from its right side. It represents the same consonant sound as the standard Kaf, typically the voiceless velar plosive /k/, but its glyphic shape is altered from the isolated form, featuring a single open tail that extends forward to join the next letter. This character is part of the Arabic Presentation Forms-B block and is primarily used in legacy text rendering systems or specialized typographic contexts to ensure proper cursive joining, as modern Unicode-aware applications typically handle such ligatures through font shaping algorithms rather than requiring individual encoded forms.
