U+29F2 "⧲" Error-Barred White Circle Unicode Character

Unicode Version 17.0

U+29F2 "⧲" Error-Barred White Circle is a specialized symbol found in the Miscellaneous Mathematical Symbols-B block, representing a white circle intersected by a vertical error bar line, which is commonly used in scientific and statistical notation to denote a data point with a specified margin of error or uncertainty in graphs and diagrams. Its design combines the open or empty circle typically indicating a measured value with a short vertical line above or through its center, signaling the range of potential variation around that measurement. This character serves as a precise typographic tool for researchers, engineers, and data analysts who require a concise, standardized way to represent error ranges in technical publications, charts, or equations without relying on custom drawing or complex formatting. While less common in everyday text, it remains an important part of Unicode's effort to encode mathematical and scientific symbols for accurate digital communication.
