U+FF57 "ｗ" Fullwidth Latin Small Letter W Unicode Character
Unicode Version 17.0
ｗ
U+FF57 "ｗ" Fullwidth Latin Small Letter W is a typographic variant of the standard Latin letter "w", designed to occupy the same horizontal space as a CJK (Chinese, Japanese, and Korean) character, making it double the width of a typical ASCII letter. It is part of the Halfwidth and Fullwidth Forms block, primarily used in East Asian text processing to ensure consistent alignment and visual harmony when Latin characters appear alongside ideographic scripts. In digital contexts, it often appears in Japanese, Chinese, or Korean text where monospaced vertical alignment is desired, and it is commonly encountered in social media posts, manga dialogues, or retro text displays for stylistic emphasis.
