U+FDA3 "ﶣ" Arabic Ligature Teh with Meem with Yeh Final Form Unicode Character

U+FDA3 "ﶣ" Arabic Ligature Teh with Meem with Yeh Final Form is a typographic ligature representing a specific connected sequence of the Arabic letters teh (ت), meem (م), and yeh (ي) in their final positional forms, meaning it appears at the end of a word where the yeh takes its final shape. This ligature is part of the Arabic Presentation Forms-B block, which contains precomposed glyphs designed for text rendering in complex scripts where cursive connections between letters could be visually or mechanically simplified. While modern Unicode encoding typically recommends using dynamic shaping through the standard Arabic characters and a shaping engine, such ligatures like U+FDA3 were historically included to support legacy systems or specific typographic traditions, and they encode combined consonants and a vowel marker (the yeh can indicate a long ī sound or grammatical endings) in a single code point for precise display.
