Lowercase Roman Numeral Four (ⅳ) is the Unicode character at U+2173 in the Number Forms block. It looks like a small roman iv and is used for outlines, chapter labels, and formal numbering.
Remember
Character ⅳ
Unicode U+2173
Hex entity ⅳ
Decimal ⅳ
CSS escape \2173
Named entity (none)
All of these produce the same glyph: ⅳ. Prefer the Unicode character (or its entities) when you need a true roman numeral; type the letters iv when you only need ordinary text.

How It Works
1. Hex:U+2173 → ⅳ in HTML. The browser turns it into ⅳ.
2. Decimal: same code point as 8563 → ⅳ. Same result as hex.
3. CSS: use \2173 in content (not an HTML entity). #point::after appends that ⅳ after the paragraph text.
4. Typed ⅳ: fine in UTF-8 pages. All four lines show the same roman numeral.
Pitfalls & Tips
Common mistakes when working with Lowercase Roman Numeral Four entities.
Named?
No named entity
HTML5 does not define &romaniv; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\2173 belongs in CSS. ⅳ / ⅳ belong in HTML.
ⅳ vs iv vs Ⅳ
Different characters
ⅳ is U+2173; letters iv are Basic Latin; uppercase Ⅳ is U+2163.
Fonts
Check the glyph
Number Forms support varies by font. If ⅳ is missing, fall back to iv or another font.
Semicolon
End references
Always finish with ; — write ⅳ, not ⅳ.
Lists
CSS list-style
For auto-numbered roman lists, prefer list-style-type: lower-roman instead of hard-coding ⅳ.
