U+216B "Ⅻ" Roman Numeral Twelve Unicode Character

Unicode Version 17.0

U+216B "Ⅻ" Roman Numeral Twelve is a precomposed glyph representing the number twelve using the Roman numeral system, composed of the symbols X for ten, I for one, and I for one, with the two ones appearing before and after the X in a non-standard sequence to form the number twelve. This character is part of the Number Forms block in Unicode, designed to provide a single encoded representation for numerals often used in clock faces, outlines, or formal contexts where a consistent typographic appearance is desired. Unlike typing the individual letters X and I separately, this unified character ensures that the numeral appears as a single cohesive unit, preventing unwanted line breaks or spacing issues in digital text. It is distinct from the standard Latin letters used to represent Roman numerals, as it is explicitly intended for numeric usage in specialized documents.
