What You'll Learn

How to display the C Reverse Roman (ↄ) in HTML using numeric references and CSS escapes. This character is U+2184 (LATIN SMALL LETTER REVERSED C) in the Number Forms block (U+2150–U+218F), added in Unicode 5.0 (2006). It is the lowercase counterpart of the Roman Numeral Reversed One Hundred (, U+2183).

The symbol is associated with the Claudian letters introduced under Emperor Claudius (41–54 CE)—an antisigma or apostrophic reversed C used in extended Roman numeral notation. There is no named HTML entity. Use ↄ, ↄ, or \2184 in CSS. Do not confuse ↄ with Latin Small Letter Open O (ɔ, U+0254).

Do
