U+13445 "𓑅" Egyptian Hieroglyph Tall Lost Sign is a specialized symbol from the Egyptian Hieroglyph Extended-A block, officially named "Egyptian Hieroglyph Tall Lost Sign," and it represents a rare or undetermined hieroglyphic form that is not fully identified in the standard Gardiner sign list, characterized by its tall shape and uncertain phonetic or semantic value. It was added to the Unicode standard as part of the ongoing effort to encode the full corpus of Egyptian hieroglyphs, including fragmentary or poorly understood signs found in ancient inscriptions, enabling scholars to digitally represent these lost or ambiguous characters for research and preservation of ancient Egyptian writing.
