U+13440 "𓑀" Egyptian Hieroglyph Mirror Horizontally Unicode Character

U+13440 "u{13440}" Egyptian Hieroglyph Mirror Horizontally is a formatting code used exclusively within the Egyptian hieroglyph block to signal that the preceding hieroglyph should be mirrored horizontally in display, flipping it from its standard orientation (usually facing right) to face the opposite direction (typically left) in order to accommodate the right-to-left or left-to-right reading direction of the text, much like a reverse control character. It does not represent a standalone glyph itself but instead modifies the appearance of an adjacent hieroglyph, ensuring that the script’s rich and directional visual flow is preserved in digital typography.
