U+216A "Ⅺ" Roman Numeral Eleven Unicode Character
Unicode Version 17.0
Ⅺ
U+216A "Ⅺ" Roman Numeral Eleven is a precomposed typographic symbol representing the number eleven in the Roman numeral system, composed of the letters X and I, which were standardized in the Unicode standard as part of the Number Forms block to facilitate digital representation and consistent rendering of traditional numerals across different platforms, ensuring that this character appears distinct from the individual letters "X" and "I" used in regular text. Its usage is primarily decorative, formal, or stylistic, such as in clock faces, outline numbering for chapters or appendices, and medieval manuscript reproduction, where maintaining the visual integrity of the ligatured form is desired.
