U+13446 "𓑆" Egyptian Hieroglyph Wide Lost Sign Unicode Character

U+13446 "𓑆" Egyptian Hieroglyph Wide Lost Sign is a specific glyph from the Egyptian Hieroglyph Extended-A block, introduced in Unicode version 16.0 to represent a sign that has been identified from fragmentary or damaged inscriptions, often found in funerary or religious contexts. This character is classified as a lost sign, meaning its phonetic or semantic value has not yet been definitively reconstructed by Egyptologists, and its wide horizontal form suggests it was used as a determinative or phonetic complement in larger texts. Its inclusion in Unicode helps preserve and encode ancient Egyptian script for digital documentation and scholarly analysis, ensuring that even partially understood hieroglyphs remain accessible for future research and comparison.
