U+FFED "■" Halfwidth Black Square Unicode Character
Unicode Version 17.0
■
U+FFED "■" Halfwidth Black Square is a monospaced punctuation symbol that occupies half the width of a standard fullwidth character, originating from the compatibility block of Unicode designed for East Asian text processing. Its appearance is a solid black square shape, and it functions primarily as a visual filler, a list marker, or a component in basic text graphics within environments that require fixed-width character spacing, such as terminal outputs or legacy computer systems. While less commonly used in modern digital fonts, it remains available for interoperability with older character sets like JIS X 0208, where it served as a typographic alternative to other block elements.
