U+FFE8 "│" Halfwidth Forms Light Vertical Unicode Character

Unicode Version 17.0

U+FFE8 "│" Halfwidth Forms Light Vertical is a typographical glyph used in East Asian text processing to represent a vertical line or stroke that occupies exactly half the width of a standard fullwidth character, making it compatible with monospaced CJK (Chinese, Japanese, and Korean) character grids. It is part of the Halfwidth and Fullwidth Forms block, which was designed to facilitate the presentation of ASCII-style characters and punctuation alongside fullwidth East Asian scripts without disrupting alignment. This specific character functions as a vertical rule or box-drawing element, often employed in terminals, legacy computer systems, or formatted text where a thin, halfwidth vertical separator is needed to maintain consistent spacing within a mixed-width layout. Its visual appearance is identical to the vertical line from the ASCII set, but its encoding ensures proper width behavior in environments that distinguish between fullwidth and halfwidth glyphs.
