Questioned equal to (≟) is the Mathematical Operators character at Unicode U+225F (QUESTIONED EQUAL TO). It marks equality that is tentative or under question — written as a ≟ b. The preferred HTML form is the named entity ≟.
Remember
Character ≟
Unicode U+225F
Named entity ≟
Hex entity ≟
Decimal ≟
CSS escape \225F
Named, numeric, and UTF-8 forms produce the same glyph: ≟. Prefer ≟ for readable, portable markup. Do not confuse it with ? (the question mark ?).

How It Works
1. Named:≟ is the preferred HTML5 entity for U+225F.
2. Hex:U+225F → ≟ in HTML. Same glyph as the named form.
3. Decimal: same code point as 8799 → ≟.
4. Direct: paste ≟ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \225F in content (not an HTML entity). The empty #point span receives that ≟ via ::after.
Pitfalls & Tips
Common mistakes when working with this math entity.
Name
Prefer ≟
Use the named entity when possible. Numeric forms are fine for generators or when names are unavailable.
Not quest
≟ ≠ ?
? is the question mark (?). ≟ is questioned equal to (≟). Names look similar — check carefully.
Not =
Not plain equals
ASCII = asserts equality. ≟ marks equality that is questioned or uncertain.
Font
Glyph coverage varies
Some fonts omit Mathematical Operators. Provide a math-capable fallback when teaching this symbol.
CSS vs HTML
Do not mix escapes
\225F belongs in CSS. ≟ / ≟ belong in HTML.
UTF-8
Declare charset
If you paste ≟ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
Compatibility
Browser Support
Questioned equal to (U+225F) and its entity forms (≟, ≟, ≟, CSS \\225F) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
Questioned Equal To (≟)
Prefer ≟, or encode with hex, decimal, or CSS escape — same glyph everywhere (when the font has it).

Bottom line: Prefer ≟ in HTML. Use ≟ or ≟ as numeric alternatives, and \\225F only inside CSS content.
Remember
Key Takeaways
Unicode: questioned equal to is U+225F (decimal 8799), Mathematical Operators.
HTML: prefer ≟ — or ≟ / ≟.
CSS: use \225F inside content for generated text.
Meaning: tentative equality — not = and not ?.
One line:U+225F → ≟ / ≟ / CSS \225F.
Frequently Asked Questions
Prefer ≟ (named). You can also use ≟ (hex), ≟ (decimal), type ≟ in UTF-8, or the CSS escape \225F in content.
U+225F (QUESTIONED EQUAL TO). Hex 225F, decimal 8799. It belongs to Mathematical Operators (U+2200–U+22FF).
Yes. HTML5 defines ≟ for U+225F. Prefer it over numeric forms when you want readable markup. Do not use ? — that is the question mark.
Use it in math and logic when equality is tentative or under question (a ≟ b). Prefer ≟ for portable HTML.
HTML entities (≟, ≟, or ≟) go in markup. The CSS escape \225F is used in stylesheets (usually in the content property of ::before/::after). Both render ≟.
≟ (≟) is questioned equal to. = is the ASCII equals sign. ? is the question mark (?). Related ideas, different characters.
