Joining Group - Kaph

Kaph is a joining group that represents the Hebrew letter kaph in its various contextual forms, such as when it appears as a final or medial character in cursive scripts like Arabic or Syriac. It determines how the letter connects to adjacent characters, specifically indicating a right-joining behavior, meaning it links to the preceding character but not the following one. This value ensures proper shaping and ligature formation in complex text rendering, preserving the visual integrity of words that include this letter. It applies to both the plain kaph and its variant with a dagesh, though not to the final form, which uses a separate joining group. The Kaph value is essential for correct bidirectional and cursive text layout, particularly in fonts that support historical or liturgical scripts.
