Remember

Unicode U+2092
Hex entity ₒ
Decimal ₒ
CSS escape \2092

Sample xₒ
Not the same o · <sub>o</sub> · combining o (U+0366)
Prefer ₒ or ₒ in HTML when you need this Unicode glyph. For most formulas, prefer semantic <sub>o</sub> instead.

Sample: xₒ
How It Works
1. Hex:U+2092 → ₒ in HTML. The browser turns it into ₒ.
2. Decimal: same code point as 8338 → ₒ. Same result as hex.
3. CSS: use \2092 in content (not an HTML entity). #point::after appends ₒ.
4. Typed: paste ₒ in a UTF-8 document when you need this Unicode subscript glyph. There is no named entity — numeric form is required when you need an entity.
Pitfalls & Tips
Common mistakes when working with Latin subscript small letter o.
Named?
No named entity
HTML5 does not define a named entity for U+2092. Use ₒ or ₒ.
Semantics
Prefer <sub> for formulas
For chemistry and math in HTML, <sub>o</sub> is usually clearer, more accessible, and easier to style than a special Unicode glyph.
Look-alikes
Not combining o
Combining Latin small letter o is U+0366 — it stacks on a base. ₒ is a spacing subscript character.
Fonts
Need subscript coverage
Some fonts omit Superscripts and Subscripts letters. Prefer a font that includes U+2092 for reliable glyphs.
CSS
Pad the CSS escape
Prefer \2092 (four hex digits). Ending the escape cleanly avoids swallowing the next character if it is a hex digit.
CSS vs HTML
Do not mix escapes
\2092 belongs in CSS strings. ₒ / ₒ belong in HTML.
Semicolon
End references
Always finish entities with ; — write ₒ, not ₒ.
