Remember
Character ⅹ
Unicode U+2179
Hex entity ⅹ

All of these produce the same glyph: ⅹ. Prefer the Unicode character (or its entities) when you need a true roman numeral; type the letter x when you only need ordinary text.

How It Works
1. Hex:U+2179 → ⅹ in HTML. The browser turns it into ⅹ.
2. Decimal: same code point as 8569 → ⅹ. Same result as hex.
3. CSS: use \2179 in content (not an HTML entity). #point::after appends that ⅹ after the paragraph text.
4. Typed ⅹ: fine in UTF-8 pages. All four lines show the same roman numeral.
Pitfalls & Tips
Common mistakes when working with Lowercase Roman Numeral Ten entities.
Named?
No named entity
HTML5 does not define &romanx; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\2179 belongs in CSS. ⅹ / ⅹ belong in HTML.
ⅹ vs x vs Ⅹ
Different characters
ⅹ is U+2179; letter x is U+0078; uppercase Ⅹ is U+2169.
Fonts
Check the glyph
Number Forms support varies by font. If ⅹ is missing, fall back to the letter x or another font.
Semicolon
End references
Always finish with ; — write ⅹ, not ⅹ.
Lists
CSS list-style
For auto-numbered roman lists, prefer list-style-type: lower-roman instead of hard-coding ⅹ.
