Superscript Eight (⁸) is the Unicode character at U+2078 in the Subscripts and Superscripts block. It looks like a small raised 8 and appears in power notation such as x⁸ and 10⁸.
Remember
Character ⁸
Unicode U+2078
Hex entity ⁸
Decimal ⁸
CSS escape \2078
Named entity (none)
All of these produce the same glyph: ⁸. Prefer the Unicode character (or its entities) when you need that exact glyph; use <sup>8</sup> when you want semantic superscript formatting instead.

How It Works
1. Hex:U+2078 → ⁸ in HTML. The browser turns it into ⁸.
2. Decimal: same code point as 8312 → ⁸. Same result as hex.
3. CSS: use \2078 in content (not an HTML entity). #point::after appends that ⁸ after the paragraph text.
4. Semantic <sup>:x<sup>8</sup> styles digit eight as a superscript. Prefer this when you need meaning, not a specific Unicode glyph.
Pitfalls & Tips
Common mistakes when working with Superscript Eight entities.
Named?
No &sup8;
HTML5 has ¹, ², and ³ only. For ⁸, use numeric forms.
CSS vs HTML
Do not mix escapes
\2078 belongs in CSS. ⁸ / ⁸ belong in HTML.
⁸ vs 8 vs ₈
Different characters
⁸ is U+2078; digit 8 is U+0038; subscript ₈ is U+2088.
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 ⁸, not ⁸.
Fonts
Check the glyph
Some fonts draw ⁸ weakly. If appearance matters, test the font or prefer <sup>.
