U+FC70 "ﱰ" Arabic Ligature Teh with Reh Final Form Unicode Character

U+FC70 "ﱰ" Arabic Ligature Teh with Reh Final Form is a typographic ligature used in the Arabic script, specifically combining the letters "teh" (ت) and "reh" (ر) into a single glyph that appears in the final position of a word. This ligature is part of the Arabic Presentation Forms-B block, designed to facilitate proper calligraphic rendering by merging adjacent characters when the first is a connecting letter and the second is a non connecting letter, as is the case with "reh". It is encoded for compatibility with older text processing systems that require precomposed forms, though in modern Unicode text, equivalent results are typically achieved through the use of combining marks and shaping engines.
