U+246F "⑯" Circled Number Sixteen Unicode Character

U+246F "⑯" Circled Number Sixteen is a typographic symbol that represents the number sixteen enclosed within a circle, and it belongs to the "Enclosed Alphanumerics" block, which was added in Unicode version 1.1 to provide monospaced, visually distinct numerals for use in lists, diagrams, and numbering systems where standard digits might not be as prominent or decorative. This character is often employed in East Asian writing systems, particularly in Japanese and Chinese contexts, for numbering items in ordered lists, such as steps in instructions, sequences in diagrams, or as part of cultural notations like the sixteen-point compass or traditional calendar markers. Its design typically mimics the shape of a simple black circle surrounding the two-digit number, though the exact appearance can vary by font, and it is distinct from other circled numbers in the same range, which continue up to circled twenty for consistency in visual presentation.
