U+2161 "Ⅱ" Roman Numeral Two Unicode Character
Unicode Version 17.0
Ⅱ
U+2161 "Ⅱ" Roman Numeral Two is a typographic representation of the number two in the ancient Roman numeral system, designed as a single glyph for use in modern digital text where consistency and clarity are needed. It is part of the Number Forms block in Unicode, which was created to standardize characters like Roman numerals, fractions, and other numeric typographic symbols. This character avoids the need to use two separate capital "I" letters, ensuring that the numeral is treated as a single logical unit in text processing, search, and display. It is commonly used in outlines, clock faces, film credits, and other contexts where a traditional Roman numeral appearance is desired.
