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

How It Works
1. Hex:U+216A → Ⅺ in HTML. The browser turns it into Ⅺ.
2. Decimal: same code point as 8554 → Ⅺ. Same result as hex.
3. CSS: use \216A in content (not an HTML entity). #point::after appends that Ⅺ after the paragraph text.
4. Typed Ⅺ: fine in UTF-8 pages. All four lines show the same roman numeral.
Pitfalls & Tips
Common mistakes when working with Roman Numeral Eleven entities.
Named?
No named entity
HTML5 does not define &romanXI; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\216A belongs in CSS. Ⅺ / Ⅺ belong in HTML.
Ⅺ vs XI vs ⅺ
Different characters
Ⅺ is U+216A; letters XI are Basic Latin; lowercase ⅺ is U+217A.
Fonts
Check the glyph
Number Forms support varies by font. If Ⅺ is missing, fall back to XI or another font.
Semicolon
End references
Always finish with ; — write Ⅺ, not Ⅺ.
Lists
CSS list-style
For auto-numbered roman lists, prefer list-style-type: upper-roman instead of hard-coding Ⅺ.
