Joining Group - CAF

CAF is a specific joining group value that represents the Arabic letter Kaf, used in certain scripts like Arabic and Syriac, where it dictates how the character connects to adjacent letters in cursive text. This value ensures that the letter takes its proper isolated, initial, medial, or final form depending on its position within a word, following the rules of Arabic script shaping. In practical terms, CAF behaves like other joining groups by defining the glyph’s connection points and whether it joins on the right, left, both sides, or neither, which is critical for correct rendering in digital typography and text layout. It is distinct from other joining group values, such as BEH or GAF, which correspond to different letter shapes and connection behaviors.
