U+FF22 "Ｂ" Fullwidth Latin Capital Letter B Unicode Character
Unicode Version 17.0
Ｂ
U+FF22 "Ｂ" Fullwidth Latin Capital Letter B is a typographic variant of the standard Latin letter B, specifically designed to occupy the same horizontal space as a CJK (Chinese, Japanese, and Korean) character, making it suitable for use in East Asian text where monospaced alignment is desired. It belongs to the Halfwidth and Fullwidth Forms block and is encoded as a fullwidth character, meaning it is twice the width of a typical Latin letter. This character is primarily employed in context where text needs to integrate with fullwidth punctuation, numbers, or other scripts, such as in Japanese or Chinese word processing, or for stylistic emphasis in digital typography.
