U+2164 "Ⅴ" Roman Numeral Five Unicode Character
Unicode Version 17.0
Ⅴ
U+2164 "Ⅴ" Roman Numeral Five is a typographic symbol representing the number five in the ancient Roman numeral system, where it derives from the Latin letter "V" and is often used in formal contexts such as clock faces, monarch names, and outline numbering. It is part of the Number Forms block in Unicode, encoded separately from the standard letter V to ensure it retains its numeric and stylistic identity across different fonts and software. This character should not be confused with the uppercase letter V, as it is specifically designed for use as a numeral, particularly in sequences like IV or VI, and it has a mirrored lowercase counterpart for dual formatting purposes in some applications.
