How It Works
1. Named:⅕ is the HTML5 name for U+2155 → ⅕.
2. Hex:⅕ inserts the same code point by hexadecimal value.
3. Decimal: same code point as 8533 → ⅕. Same visual as named/hex.
4. CSS: use \2155 in content (not an HTML entity). #point::after appends ⅕.
5. Typed: paste ⅕ in a UTF-8 document when you need the one-fifth glyph as one character.
Pitfalls & Tips
Common mistakes when working with fraction 1 by 5.
Name
Prefer ⅕
The named entity is clear and standard. Avoid inventing names like &onefifth;.
1/5
Not three characters
Typing 1/5 creates three code points. ⅕ is one Number Forms character.
⅖
Not two fifths
Two fifths is ⅖ (U+2156). Use it when you mean 2/5, not 1/5.
Font
Font coverage
Some fonts omit Number Forms fractions. If ⅕ is missing, fall back to 1/5 or a font with Number Forms coverage.
CSS vs HTML
Do not mix escapes
\2155 belongs in CSS strings. ⅕ / ⅕ / ⅕ belong in HTML.

Add accessible text
Screen readers may not announce ⅕ clearly. Prefer aria-label="one fifth" or nearby prose when the fraction carries meaning.
Semicolon
End references
Always finish entities with ; — write ⅕, not &frac15.
