U+216E "Ⅾ" Roman Numeral Five Hundred Unicode Character
U+216E "Ⅾ" Roman Numeral Five Hundred is a specific typographic representation of the numeric value 500, encoded in the Number Forms block of the Unicode standard for compatibility with legacy character sets and for use in contexts where a distinct, single glyph for the Roman numeral is preferred over the standard composite form of "D". It is categorized as a numeric digit and is intended for use in precomposed text, such as in ancient manuscripts, clock faces, or formal document outlines, where the visual appearance of a unified character rather than a sequence of letters is desired. This character differs from the capital letter D (U+0044) in its semantic meaning as a numeral and in its possible stylistic rendering, ensuring that digital text can preserve the intended numeric identity across different platforms and fonts.
