U+FC71 "ﱱ" Arabic Ligature Teh with Zain Final Form Unicode Character

U+FC71 "ﱱ" Arabic Ligature Teh with Zain Final Form is a typographic presentation form used in Arabic script calligraphy and typesetting to represent the specific ligature of the letters "teh" (ﺕ) and "zain" (ﺯ) when they appear together at the end of a word. This character is part of the Unicode standard’s "Arabic Presentation Forms-A" block, which was primarily designed to support legacy text and high-quality rendering of Arabic script, where such ligatures avoid the typical spacing and joining issues that arise in standard encoded text. It is not intended for general modern typing but rather for specialized contexts such as religious texts, historical documents, or customized visual layouts.
