U+FC51 "ﱑ" Arabic Ligature Heh with Jeem Isolated Form Unicode Character

U+FC51 "ﱑ" Arabic Ligature Heh with Jeem Isolated Form is a typographic ligature found in the Arabic script block, specifically representing the joined combination of the letters heh (ه) and jeem (ج) when they appear in their isolated context. This ligature is part of the Arabic Presentation Forms-A range, which encodes precomposed forms of cursive writing to facilitate the display of traditional calligraphic styles in digital text. Its primary use is in rendered Arabic script where the two characters are seamlessly connected into a single glyph for aesthetic or historical precision, though it is not typically employed in modern plain text due to the availability of dynamic shaping algorithms in Unicode-aware fonts.
