U+FF99 "ﾙ" Halfwidth Katakana Letter Ru Unicode Character
Unicode Version 17.0
ﾙ
U+FF99 "ﾙ" Halfwidth Katakana Letter Ru is a character from the CJK compatibility block, specifically representing a narrow version of the fullwidth katakana character "ル", which is used in Japanese writing to denote the syllable "ru". This halfwidth character was historically designed to fit within the fixed-width grids of older computer systems and text terminals, often used in conjunction with other halfwidth katakana for compatibility with digital environments that lacked sufficient space for fullwidth characters. Its visual appearance is identical to the standard katakana "ル" but occupies half the character width, making it a practical typographic variant for legacy data processing or constrained display contexts.
