U+2180 "ↀ" Roman Numeral One Thousand C D Unicode Character
Unicode Version 17.0
U+2180 "ↀ" Roman Numeral One Thousand C D is a historical numeric symbol representing the value of one thousand in the Roman numeral system, specifically depicted as an overlay or ligature of the letters C, I, and sometimes D to denote 1,000 (where "ↀ" evolved from a simpler form of encircling or modifying the standard "M" or other numerals). It is part of the Unicode block "Number Forms" and was included to support ancient or medieval epigraphic and manuscript texts where this variant form of the numeral was used, distinct from the more common "M" for 1000. This character serves as a typographic and historical reference, preserving an alternative notation that appears in certain old inscriptions and documents, and is encoded primarily for compatibility and scholarly use rather than for modern everyday writing.
