U+FF61 "｡" Halfwidth Ideographic Full Stop Unicode Character
Unicode Version 17.0
｡
U+FF61 "｡" Halfwidth Ideographic Full Stop is a punctuation mark derived from the fullwidth Japanese ideographic period (。" U+3002), but scaled to occupy a single halfwidth character cell for compatibility with East Asian text processing systems that use a fixed-width font lattice. It is primarily used to mark the end of a sentence in Japanese and occasionally in Chinese or Korean text when space is limited or when adhering to halfwidth character sets. Unlike its fullwidth counterpart, this character matches the width of standard Latin letters and digits, making it suitable for mixed-script contexts where alignment and character density must be preserved.
