U+FF64 "、" Halfwidth Ideographic Comma Unicode Character

Unicode Version 17.0

U+FF64 "、" Halfwidth Ideographic Comma is a punctuation mark used primarily in East Asian typography, particularly for Japanese and Chinese text, where it represents a halfwidth version of the standard ideographic comma (、). It occupies a single character width instead of the fullwidth form, making it suitable for use in contexts like monospaced fonts, legacy terminal displays, or mixed text with halfwidth Latin characters. This character helps maintain visual consistency in environments where character spacing is fixed or limited.
