Degree Fahrenheit (℉) is the Unicode character at U+2109 in the Letterlike Symbols block. Official name: DEGREE FAHRENHEIT. It is a single symbol for Fahrenheit temperature — not the same as degree sign + letter F.

How It Works
1. Hex:U+2109 → ℉ in HTML → ℉.
2. Decimal: same code point as 8457 → ℉. Same result as hex.
3. CSS: use \2109 in content (not an HTML entity). #point::after appends that ℉ after the paragraph text.
4. Typed: in a UTF-8 page you can paste ℉ directly.
5. Alternative:°F is degree sign (U+00B0) plus the letter F — two characters, often better for fonts and accessibility.
Pitfalls & Tips
Common mistakes when working with Degree Fahrenheit.
Named?
No &fahrenheit;
HTML5 has no named entity for U+2109. Use numeric forms, or °F as an alternative.
°F
Symbol vs composition
℉ is one character. °F is two. Prefer °F when font or a11y support for U+2109 is uncertain.
℃
Not Celsius
℃ is degree Celsius (U+2103). Do not mix the two symbols.
CSS vs HTML
Do not mix escapes
\2109 belongs in CSS strings. ℉ / ℉ belong in HTML.
Fonts
Letterlike coverage
Some fonts omit U+2109 and show a box. Fall back to °F if needed.
Semicolon
End references
Always finish with ; — write ℉, not ℉.
