Roman Numeral One Hundred (Ⅽ) is the Unicode character at U+216D in the Number Forms block. It looks like an uppercase roman C and is used for outlines, chapter labels, and formal numbering.
Remember
Character Ⅽ
Unicode U+216D
Hex entity Ⅽ
Decimal Ⅽ
CSS escape \216D
Named entity (none)
All of these produce the same glyph: Ⅽ. Prefer the Unicode character (or its entities) when you need a true roman numeral; type the letter C when you only need ordinary text.

How It Works
1. Hex:U+216D → Ⅽ in HTML. The browser turns it into Ⅽ.
2. Decimal: same code point as 8557 → Ⅽ. Same result as hex.
3. CSS: use \216D in content (not an HTML entity). #point::after appends that Ⅽ after the paragraph text.
4. Typed Ⅽ: fine in UTF-8 pages. All four lines show the same roman numeral.
Pitfalls & Tips
Common mistakes when working with Roman Numeral One Hundred entities.
Named?
No named entity
HTML5 does not define &romanC; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\216D belongs in CSS. Ⅽ / Ⅽ belong in HTML.
Ⅽ vs C vs ⅽ
Different characters
Ⅽ is U+216D; letter C is U+0043; lowercase ⅽ is U+217D; reverse Ↄ is U+2183.
Fonts
Check the glyph
Number Forms support varies by font. If Ⅽ is missing, fall back to the letter C or another font.
Semicolon
End references
Always finish with ; — write Ⅽ, not Ⅽ.
Lists
CSS list-style
For auto-numbered roman lists, prefer list-style-type: upper-roman instead of hard-coding Ⅽ.
