U+FFEE "○" Halfwidth White Circle Unicode Character
Unicode Version 17.0
○
U+FFEE "○" Halfwidth White Circle is a typographic symbol belonging to the Halfwidth and Fullwidth Forms block, designed to occupy half the width of a standard fullwidth character for compatibility with legacy East Asian text layouts and monospaced fonts. It represents a hollow or white circle, typically used as a placeholder, a marking symbol, or a component in visual patterns and diagrams, particularly in contexts where narrow spacing is required. This character is distinct from its fullwidth counterpart, U+25CB, and is often employed in terminal interfaces, retro computing, or CJK (Chinese, Japanese, Korean) text to maintain consistent character alignment without expanding line length.
