U+FBFF "ﯿ" Arabic Letter Farsi Yeh Medial Form Unicode Character

Unicode Version 17.0

ﯿ

U+FBFF "ﯿ" Arabic Letter Farsi Yeh Medial Form is a presentation form of the Arabic letter Yeh, specifically adapted for the Persian or Farsi language, used when the character appears in the middle of a word. This glyph is part of the Arabic Presentation Forms-B block, which is designed for compatibility with older text processing systems and does not have a canonical decomposition equivalent to a standard Arabic letter, as its shape is contextually determined by surrounding characters. Unlike the basic Arabic Yeh, which can connect differently, this medial form appears with a distinct curved tail or hook on both sides, ensuring proper visual joining in bidirectional text. It is primarily employed in modern Persian orthography, where it represents a long "i" sound or the consonant "y" within a word, and is essential for correct rendering in specialized typographic contexts, though modern Unicode algorithms typically substitute standard Arabic Yeh variants automatically.
