U+FC58 "ﱘ" Arabic Ligature Yeh with Meem Isolated Form Unicode Character
U+FC58 "ﱘ" Arabic Ligature Yeh with Meem Isolated Form is a typographic ligature used in the Arabic script, representing the combined calligraphic form of the letters Yeh (ي) and Meem (م) in their isolated position. This character belongs to the Unicode block of Arabic Presentation Forms-A, which exists primarily to support older text processing systems and precise typesetting of the Quran and other classical Arabic texts. It is designed to maintain the visual coherence of cursive Arabic writing by rendering a single connected glyph instead of two separate characters, helping to preserve the fluent strokes of the script in specific typographic contexts. However, this ligature is considered a presentation form rather than a standard character for modern plain text, and its use is generally discouraged in favor of the standard Unicode encoding with a Zero Width Joiner or relying on modern font shaping engines for rendering.
