U+FF40 "`" Fullwidth Grave Accent Unicode Character

Unicode Version 17.0

U+FF40 "`" Fullwidth Grave Accent is a typographic variant of the standard grave accent, designed to occupy the same width as a fullwidth character, typically used in East Asian scripts like Chinese, Japanese, and Korean when mixed with monospaced or CJK fonts. It is part of the Halfwidth and Fullwidth Forms block, where it corresponds to the common ASCII grave accent but with a wider visual footprint, often employed in text processing, code, or formatting where alignment with other fullwidth characters is required. Unlike its combining form, this character stands alone as a spacing symbol, used in contexts such as indicating stress, tone, or as a diacritic in romanized text, though its primary role is to maintain visual harmony in East Asian digital typography.
