U+FF9B "ﾛ" Halfwidth Katakana Letter Ro Unicode Character
Unicode Version 17.0
ﾛ
U+FF9B "ﾛ" Halfwidth Katakana Letter Ro is a typographic variant of the fullwidth Katakana character ロ, which represents the syllable "ro" in the Japanese writing system. Designed to occupy a single monospaced character cell, this halfwidth form was commonly used in older computer systems, digital displays, and telecommunication text where space was limited, such as in shift-JIS encoded environments or vintage terminals. While modern Unicode text typically defaults to fullwidth Katakana for clarity and balance, the halfwidth version remains supported for legacy compatibility and is rarely used in contemporary Japanese writing except in specialized contexts like precise formatting or retro computing.
