C Reverse Roman (ↄ) is the Unicode character at U+2184 in the Number Forms block (official name: LATIN SMALL LETTER REVERSED C). It is a mirrored lowercase c, linked to Claudian-letter / classical notation, and the lowercase pair of reversed one hundred (Ↄ).
Remember
Character ↄ
Unicode U+2184
Hex entity ↄ
Decimal ↄ
CSS escape \2184
Named entity (none)
All of these produce the same glyph: ↄ. Prefer the Unicode character (or its entities) when you need that exact reversed form; use letter c for ordinary text.

How It Works
1. Hex:U+2184 → ↄ in HTML. The browser turns it into ↄ.
2. Decimal: same code point as 8580 → ↄ. Same result as hex.
3. CSS: use \2184 in content (not an HTML entity). #point::after appends that ↄ after the paragraph text.
4. Typed ↄ: fine in UTF-8 pages. All four lines show the same glyph.
Pitfalls & Tips
Common mistakes when working with C Reverse Roman entities.
Named?
No named entity
HTML5 does not define &crevroman; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\2184 belongs in CSS. ↄ / ↄ belong in HTML.
ↄ vs Ↄ vs ɔ
Different characters
ↄ is U+2184; uppercase pair Ↄ is U+2183; open o ɔ is U+0254.
Fonts
Check the glyph
Number Forms support varies by font. If ↄ is missing, use a fallback font or explain the symbol in nearby text.
Semicolon
End references
Always finish with ; — write ↄ, not ↄ.
Clarity
Add context
Many readers will not recognize ↄ. Label it on first use when meaning matters.

Key Takeaways
Unicode: C reverse roman is U+2184 (decimal 8580).
HTML: use ↄ or ↄ when you need an entity.
CSS: use \2184 inside content for generated text.
Watch out: ↄ ≠ Ↄ ≠ ɔ (small reversed C ≠ uppercase pair ≠ open o).
One line:U+2184 → ↄ / ↄ / CSS \2184, or paste ↄ.
Frequently Asked Questions
Use ↄ (hex), ↄ (decimal), or the CSS escape \2184 in the content property. All render ↄ. You can also paste ↄ directly when your file is UTF-8.
U+2184 (hex 2184, decimal 8580). Unicode names it LATIN SMALL LETTER REVERSED C. It belongs to the Number Forms block.
No. HTML5 does not define a named entity for ↄ. Use numeric references like ↄ or ↄ.
ↄ (U+2184) is the small reversed C. Ↄ (U+2183) is roman numeral reversed one hundred (uppercase pair). ɔ (U+0254) is Latin small letter open o — a different IPA letter.
HTML entities (ↄ or ↄ) go in markup. The CSS escape \2184 is used in stylesheets (usually in the content property of ::before/::after). Both render ↄ.
Use it for Claudian-letter notation, classical typography, or when you specifically need the small reversed-C glyph. For ordinary text, prefer letter c.
