What Is the Roman Numeral Reversed One Hundred Entity?
Roman Numeral Reversed One Hundred (Ↄ) is the Unicode character at U+2183 in the Number Forms block. It looks like a mirrored C and appears in classical typography and specialized notation for the value 100.
Remember
Character Ↄ
Unicode U+2183
Hex entity Ↄ
Decimal Ↄ
CSS escape \2183
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 or roman Ⅽ for ordinary roman-100 text.

How It Works
1. Hex:U+2183 → Ↄ in HTML. The browser turns it into Ↄ.
2. Decimal: same code point as 8579 → Ↄ. Same result as hex.
3. CSS: use \2183 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 Roman Numeral Reversed One Hundred entities.
Named?
No named entity
HTML5 does not define &revroman100; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\2183 belongs in CSS. Ↄ / Ↄ belong in HTML.
Ↄ vs C vs Ⅽ
Different characters
Ↄ is U+2183; letter C is U+0043; roman Ⅽ is U+216D.
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.
