Superscript Nine (⁹) is the Unicode character at U+2079 in the Subscripts and Superscripts block. It looks like a small raised 9 and appears in power notation such as x⁹ and 10⁹.
Remember
Character ⁹
Unicode U+2079
Hex entity ⁹
Decimal ⁹
CSS escape \2079
Named entity (none)
All of these produce the same glyph: ⁹. Prefer the Unicode character (or its entities) when you need that exact glyph; use <sup>9</sup> when you want semantic superscript formatting instead.

How It Works
1. Hex:U+2079 → ⁹ in HTML. The browser turns it into ⁹.
2. Decimal: same code point as 8313 → ⁹. Same result as hex.
3. CSS: use \2079 in content (not an HTML entity). #point::after appends that ⁹ after the paragraph text.
4. Semantic <sup>:x<sup>9</sup> styles digit nine as a superscript. Prefer this when you need meaning, not a specific Unicode glyph.
Pitfalls & Tips
Common mistakes when working with Superscript Nine entities.
Named?
No &sup9;
HTML5 has ¹, ², and ³ only. For ⁹, use numeric forms.
CSS vs HTML
Do not mix escapes
\2079 belongs in CSS. ⁹ / ⁹ belong in HTML.
⁹ vs 9 vs ₉
Different characters
⁹ is U+2079; digit 9 is U+0039; subscript ₉ is U+2089.
Glyph vs tag
Choose intentionally
Use the Unicode glyph for exact look; use <sup> for semantic superscript on any text.
Semicolon
End references
Always finish with ; — write ⁹, not ⁹.
Fonts
Check the glyph
Some fonts draw ⁹ weakly. If appearance matters, test the font or prefer <sup>.
