U+FC54 "ﱔ" Arabic Ligature Heh with Yeh Isolated Form Unicode Character

U+FC54 "ﱔ" Arabic Ligature Heh with Yeh Isolated Form is a typographic ligature found within the Arabic Presentation Forms-A block, designed to represent the graphic fusion of the letters heh (ه) and yeh (ي) when they appear together in an isolated position within handwritten or calligraphic Arabic text. This character serves as a visual convenience for rendering a specific cursive combination that occurs in certain writing styles, allowing the two letters to be displayed as a single connected glyph rather than as separate characters. It is important to note that U+FC54 is part of a legacy encoding scheme intended primarily for compatibility with older text rendering systems, and modern Unicode usage generally encourages the use of standard Arabic characters with proper shaping algorithms to achieve the same ligature effect.
