How It Works
1. Hex:↉ inserts code point U+2189 → ↉.
2. Decimal: same code point as 8585 → ↉. Same visual as hex.
3. CSS: use \2189 in content (not an HTML entity). #point::after appends ↉.
4. Typed: paste ↉ in a UTF-8 document when you need the vulgar fraction as one character.
Pitfalls & Tips
Common mistakes when working with fraction 0 by 3.
Name
No named entity
There is no HTML5 named entity for U+2189. Use ↉ or ↉. Do not invent &frac03;.
0/3
Not three characters
Typing 0/3 creates three code points. ↉ is one Number Forms character.
Font
Font coverage
Some fonts omit rare vulgar fractions. If ↉ is missing, fall back to 0/3 or a font with Number Forms coverage.
Value
Mathematically zero
Zero thirds equals 0. Prefer the glyph only when you want the fraction appearance, not a numeric zero digit.
CSS vs HTML
Do not mix escapes
\2189 belongs in CSS strings. ↉ / ↉ belong in HTML.

Add accessible text
Screen readers may not announce ↉ clearly. Prefer aria-label="zero thirds" or nearby prose when the fraction carries meaning.
Semicolon
End references
Always finish entities with ; — write ↉, not ↉.
