What Is Square Image Of Not Equal To?

Square image of or not equal to (⋤) is the Unicode character at U+22E4 in Mathematical Operators. Official name: SQUARE IMAGE OF OR NOT EQUAL TO. It is a square-style image-of relation that also marks inequality.

Remember
Character     ⋤
Unicode       U+22E4
Named entity  (none)
Hex entity    ⋤
Decimal       ⋤
CSS escape    \22E4
Not the same  ⊏ · ⊑ · ⋢

Prefer ⋤ or ⋤ in HTML markup. You can also type ⋤ in UTF-8. For plain square image of, use ⊏ (⊏) instead.

Try It Yourself

How It Works

1. Hex: U+22E4 → &#x22E4; in HTML. Preferred numeric form when you need an entity.

2. Decimal: same code point as 8932 → &#8932;. Same glyph as hex.

3. CSS: use \22E4 in content (not an HTML entity). #point::after appends that ⋤ after the paragraph text.

4. Typed / notation: paste ⋤ in UTF-8, or write A &#x22E4; B for a short relation.

5. No named entity: HTML5 does not define a name for U+22E4 — use numeric references or type the character.

Pitfalls & Tips

Common mistakes when working with U+22E4.

vs ⊏

Not plain square image of

U+228F (⊏, &sqsub;) is the basic relation. U+22E4 adds the “not equal” sense.

vs ⊑

Not or-equal form

⊑ (U+2291, &sqsube;) means square image of or equal to — the opposite inequality flavor.

vs ⋢

Not &nsqsube;

⋢ (U+22E2) is “not square image of or equal to.” Different character and different named entity.

Named

No named HTML entity

There is no &sqsubneq; for U+22E4. Use &#x22E4; or &#8932;.

CSS vs HTML

Do not mix escapes

\22E4 belongs in CSS strings. &#x22E4; / &#8932; belong in HTML.

A11y

Name the relation in context

Screen readers may announce this symbol unevenly. Prefer nearby text when the glyph carries meaning alone.

Compatibility

Browser Support

Square image of or not equal to (U+22E4) and its entity forms (&#x22E4;, &#8932;, CSS \\22E4) are supported in all mainstream browsers. Visible glyphs depend on Mathematical Operators font coverage.

✓ Universal support

Square Image Of Not Equal To (&#x22E4;)

Encode with hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

Bottom line: Prefer &#x22E4; or &#8932; in HTML. Use \\22E4 only inside CSS content. There is no named entity.

Remember

Key Takeaways

  • Unicode: this relation is U+22E4 (decimal 8932) — glyph ⋤.
  • HTML: no named entity — use &#x22E4; / &#8932; / type ⋤.
  • CSS: use \22E4 inside content for generated text.
  • Meaning: ⋤ is “or not equal” — not ⊏ (&sqsub;), not ⊑.

One line: U+22E4 → &#x22E4; / &#8932; / CSS \22E4 (no named entity).

Frequently Asked Questions

U+22E4 (SQUARE IMAGE OF OR NOT EQUAL TO). Hex 22E4, decimal 8932. It belongs to Mathematical Operators (U+2200–U+22FF).
No. Use numeric references &#x22E4; or &#8932;, or type ⋤ in UTF-8.
No. ⋤ is U+22E4 (square image of or not equal to). ⊏ is U+228F (&sqsub;). ⊑ is U+2291 (&sqsube;).
Use it when your math notation needs a square-image-of relation that is not equal — not as a substitute for plain ⊏ or ⊑.
HTML entities (&#8932; or &#x22E4;) go in markup. The CSS escape \22E4 goes in stylesheet strings (usually content on ::before/::after).

Did you know?
