U+FF1F "？" Fullwidth Question Mark Unicode Character
Unicode Version 17.0
？
U+FF1F "？" Fullwidth Question Mark is a variant of the standard question mark designed for use in East Asian typography, where it occupies the same width as a fullwidth character, typically twice that of a regular Latin glyph. It belongs to the Halfwidth and Fullwidth Forms Unicode block and is commonly employed in Chinese, Japanese, and Korean text to maintain visual alignment and consistency within monospaced or ideographic scripts. This character serves the same grammatical function as its standard counterpart, indicating a question, but its wider appearance ensures it blends harmoniously with other fullwidth punctuation and characters in digital and printed documents.
