U+FCA3 "ﲣ" Arabic Ligature Teh with Khah Initial Form Unicode Character

U+FCA3 "ﲣ" Arabic Ligature Teh with Khah Initial Form is a typographic glyph used in the Arabic script, representing a ligature of the letters Teh and Khah joined together in their initial form. This character is part of the Arabic Presentation Forms-A block, which was designed to support complex calligraphic and typesetting needs in older systems, allowing for the display of a single connected shape where the two letters appear as a cohesive unit at the beginning of a word. While modern Unicode typically relies on dynamic shaping via the Arabic joining algorithm, this precomposed ligature remains available for legacy text or specialized orthographic contexts.
