Roman Numeral Five Hundred (Ⅾ) is the Unicode character at U+216E in the Number Forms block. It looks like a capital roman D and is used for outlines, chapter labels, and formal numbering for the value 500.
Remember
Character Ⅾ
Unicode U+216E
Hex entity Ⅾ
Decimal Ⅾ
CSS escape \216E
Named entity (none)
All of these produce the same glyph: Ⅾ. Prefer the Unicode character (or its entities) when you need a true roman numeral; type the letter D when you only need ordinary text.

How It Works
1. Hex:U+216E → Ⅾ in HTML. The browser turns it into Ⅾ.
2. Decimal: same code point as 8558 → Ⅾ. Same result as hex.
3. CSS: use \216E in content (not an HTML entity). #point::after appends that Ⅾ after the paragraph text.
4. Typed Ⅾ: fine in UTF-8 pages. All four lines show the same roman numeral.
Pitfalls & Tips
Common mistakes when working with Roman Numeral Five Hundred entities.
Named?
No named entity
HTML5 does not define &romanD; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\216E belongs in CSS. Ⅾ / Ⅾ belong in HTML.
Ⅾ vs D vs ⅾ
Different characters
Ⅾ is U+216E; letter D is Basic Latin; lowercase ⅾ is U+217E.
Fonts
Check the glyph
Number Forms support varies by font. If Ⅾ is missing, fall back to D or another font.
Semicolon
End references
Always finish with ; — write Ⅾ, not Ⅾ.
Lists
CSS list-style
For auto-numbered roman lists, prefer list-style-type: upper-roman instead of hard-coding Ⅾ.
