U+FC10 "ﰐ" Arabic Ligature Teh with Yeh Isolated Form Unicode Character

U+FC10 "ﰐ" Arabic Ligature Teh with Yeh Isolated Form is a typographic ligature found in the Arabic Presentation Forms-A block, representing the isolated form of the combined letters "teh" (ت) and "yeh" (ي). This character is not intended for general text interchange but rather for compatibility with legacy Arabic text rendering systems that require specific glyph forms for two-letter combinations. It visually joins a "teh" to a following "yeh," often used in contexts like Arabic calligraphy or older font standards where such precomposed forms simplify layout. Modern Unicode practice recommends using the individual characters with standard shaping algorithms instead of this specialized ligature.
