Triple Tilde (≋) is the Mathematical Operators character at Unicode U+224B (TRIPLE TILDE). HTML5 names it ≋. Use it for specialized logic and mathematical relations.
Remember
Character ≋
Unicode U+224B
Named entity ≋
Hex entity ≋
Decimal ≋
CSS escape \224B
Not the same ∼ (∼) · ~~~ · ‴ (‴)
Named, hex, decimal, CSS, and a typed character all produce the same glyph: ≋. Prefer ≋ in HTML markup. For the common tilde operator see ∼ (∼).
Built with Named: ≋
Built with Hex: ≋
Built with Decimal: ≋
Built with CSS: ≋
Typed: ≋
Logic: A ≋ B
How It Works
1. Named:≋ is the preferred HTML5 name for U+224B → ≋.
2. Hex:≋ inserts the same code point. Same visual as named.
3. Decimal: same code point as 8779 → ≋.
4. CSS: use \224B in content (not an HTML entity). #point::after appends ≋.
5. Typed: paste ≋ in a UTF-8 document, or write A ≋ B for a relation.
Pitfalls & Tips
Common mistakes when working with Triple Tilde.
Named
Prefer ≋
≋ is the clear HTML5 named form. It is case-sensitive — write ≋, not ≋.
Look-alikes
≋ ≠ ∼ ≠ ~~~
U+224B is one character. Do not fake it with three ASCII tildes. The common tilde operator is ∼ (∼).

Add context
A lone ≋ may be unclear. Pair it with wording such as “triple tilde relation” or an accessible name for screen readers.
Confusion
Not prime or between
Do not confuse ≋ with triple prime (‴) or between (≬) — different characters for different purposes.
CSS vs HTML
Do not mix escapes
\224B belongs in CSS. ≋ / ≋ / ≋ belong in HTML.
Semicolon
End references
Always finish with ; — write ≋, not &apid.
Compatibility
Browser Support
Triple Tilde (U+224B) and its entity forms (≋, ≋, ≋, CSS \\224B) are supported in all modern browsers. Glyph coverage depends on the font.
✓ Universal encoding
Triple Tilde (≋)
Encode with named, hex, decimal, or CSS escape — or type ≋ directly in UTF-8 HTML. Prefer ≋.

Bottom line: Prefer ≋ for readable HTML. Use \\224B only inside CSS content. Do not confuse with ∼ or three ASCII tildes.
Remember
Key Takeaways
Unicode: this symbol is U+224B (decimal 8779) — triple tilde.
HTML: prefer ≋ — or use ≋ / ≋.
CSS: use \224B inside content for generated math markers.
Watch out: not the same as ∼, between, or three ASCII tildes.
Use ≋ (named), ≋ (hex), ≋ (decimal), or the CSS escape \224B in the content property. All render ≋. Prefer ≋ for readable markup.
U+224B (TRIPLE TILDE). Hex 224B, decimal 8779, named entity ≋. It belongs to Mathematical Operators (U+2200–U+22FF).
Yes. HTML5 defines ≋ for U+224B. It is case-sensitive — write ≋, not ≋.
U+224B is TRIPLE TILDE (≋), a specialized relation. U+223C is TILDE OPERATOR (∼), the common single tilde/similarity symbol. Do not swap them.
Use it for logic expressions, formal maths, and specialized relation notation that specifically needs the triple-tilde glyph. Prefer ≋ instead of three ASCII tildes.
HTML entities (≋, ≋, or ≋) go in markup. The CSS escape \224B is used in stylesheets (usually in the content property of ::before/::after). Both render ≋.

Did you know?
Triple Tilde is Unicode U+224B (decimal 8779) — glyph ≋ (TRIPLE TILDE) in Mathematical Operators. HTML5 names it ≋ (case-sensitive). Prefer it for specialized logic and mathematical relations. Do not confuse it with the tilde operator (∼, U+223C), between (≬, U+226C), or three ASCII tildes (~~~).
