About the vulgar fraction one ninth symbol

This character is not an emoji and appears in plain text across various writing systems, though its use is less common than more familiar fractions like one half or one quarter. It is occasionally encountered in contexts such as stock market reports, ingredient lists, or specialized mathematical typesetting where exact fractional values are needed.
