U+FEF1 "ﻱ" Arabic Letter Yeh Isolated Form Unicode Character

Unicode Version 17.0

U+FEF1 "ﻱ" Arabic Letter Yeh Isolated Form is a presentation form of the Arabic letter Yeh, specifically designed for use in contexts requiring the isolated visual shape of the character, such as when it appears alone or after most connectors in Arabic script. It represents the consonant sound "y" or the long vowel "ee" and is part of the Arabic Presentation Forms-B block, which contains variants of standard Arabic letters to accommodate positional forms in text. This character is typically used in legacy systems or specialized rendering environments where standard Unicode encoding (like U+064A ي) does not automatically produce the correct ligature or shape, ensuring accurate typographic display for applications like digital typesetting or historical text processing.
