Unicode Version 17.0

U+FDBB "ﶻ" Arabic Ligature Kaf with Meem with Meem Final Form is a typographic ligature found in the Arabic script, designed to represent the combination of the letters Kaf (ك), Meem (م), and another Meem (م) in their final positional form within a word. This ligature is part of the Arabic Presentation Forms-B block, which contains complex character shapes used for aesthetic or calligraphic rendering in Arabic text processing. It reflects the tradition in Arabic calligraphy of merging adjacent letters into a single glyph to enhance visual flow and compactness, often seen in religious, formal, or decorative writing contexts. The character is not used for standard modern Arabic text but rather for specialized display systems, such as in Quranic manuscripts or historical typesetting, where preserving the precise cursive appearance of specific letter sequences is important for readability or artistic tradition.
