U+FF9A "レ" Halfwidth Katakana Letter Re Unicode Character

Unicode Version 17.0

U+FF9A "レ" Halfwidth Katakana Letter Re is a typographic variant of the fullwidth Katakana character レ, representing the Japanese syllabic sound "re." It belongs to the Halfwidth and Fullwidth Forms block of Unicode, where characters are encoded at half the width of their standard counterparts for compatibility with legacy computer systems and text environments that used fixed-width character grids, such as early terminals or certain CJK (Chinese, Japanese, Korean) fonts. This halfwidth form maintains the same phonetic value as the fullwidth version but occupies a single byte space in systems where fullwidth characters require two bytes, making it useful for precise text alignment or when mixing with ASCII characters in contexts like old video game displays or teletext.
