U+FF73 "ウ" Halfwidth Katakana Letter U Unicode Character
Unicode Version 17.0
ウ
U+FF73 "ウ" Halfwidth Katakana Letter U is a typographic variant of the standard fullwidth katakana character ウ, which represents the vowel sound "u" in the Japanese syllabary. It occupies a single character width in monospaced text, making it half the width of its fullwidth counterpart, and was originally designed for compatibility with legacy computer systems and terminals that used a fixed-width grid for displaying characters. This halfwidth form is part of the Halfwidth and Fullwidth Forms Unicode block and is primarily used in contexts where space efficiency is important, such as in old-style ASCII environments or when mixing with other halfwidth characters for aesthetic or technical reasons.
