U+FCB6 "ﲶ" Arabic Ligature Dad with Khah Initial Form Unicode Character

U+FCB6 "ﲶ" Arabic Ligature Dad with Khah Initial Form is a typographic ligature used in the Arabic script, specifically representing the connected initial forms of the letters "Dad" (ض) and "Khah" (خ) as they appear at the beginning of a word. This ligature is part of the Arabic Presentation Forms-B block, which was originally included in Unicode to accommodate legacy font rendering and orthographic conventions rather than for modern text interchange. The joining of these two distinct letters into a single glyph helps preserve the visual flow and aesthetics of traditional Arabic calligraphy, particularly in contexts where precise textual presentation is important.
