Halfwidth Katakana Letter Ri

ﾘ is the narrow compatibility form of リ, read “ri,” not a different syllable. Its computer-era story begins with JIS C 6220 (1969), whose limited code space put katakana into narrow cells beside Latin text; later double-byte standards carried full Japanese writing, while the narrow form remained for compatibility and field-specific input. Use it when a field requests half-width katakana; otherwise choose リ.
