U+FD51 "ﵑ" Arabic Ligature Teh with Hah with Jeem Final Form Unicode Character

U+FD51 "ﵑ" Arabic Ligature Teh with Hah with Jeem Final Form is a complex typographic glyph used in the Arabic script, representing a mandatory ligature that combines the letters teh (ت), hah (ح), and jeem (ج) into a single connected form positioned at the end of a word. This character belongs to the Arabic Presentation Forms-A block, which was primarily designed for backward compatibility with older text processing systems that required precomposed ligatures rather than relying on modern shaping engines. In standard Unicode text, the sequence of these three letters would typically be rendered automatically by a font's shaping logic, but U+FD51 preserves a specific visual appearance from earlier digital fonts and typesetting traditions. As a final form ligature, it ensures that the combined characters maintain proper cursive joining and spacing in contexts where the three consonants appear together at the end of a syllable.
