U+1F157 "🅗" Negative Circled Latin Capital Letter H Unicode Character

U+1F157 "🅗" Negative Circled Latin Capital Letter H is a typographic symbol that represents the letter H enclosed within a solid black circle with reversed or negative coloring, meaning the letter appears in white against a dark background. Part of the Enclosed Alphanumeric Supplement block, it was introduced in Unicode version 6.0 in 2010 and is designed for use in visual contexts such as signage, maps, interface icons, or decorative text where a bold, enclosed letter H is needed to convey information like a label, identifier, or marker. The character is distinct from regular uppercase H and other circled letter variants, offering a high-contrast appearance suitable for emphasis or accessibility in digital and print media.
