What Is the Not Square Original Of Equal To Entity?

Not square original of equal to (⋣) is the Mathematical Operators character at Unicode U+22E3 (NOT SQUARE ORIGINAL OF OR EQUAL TO). It negates the square-original-of-or-equal relation (⊒, ⊒) used in order theory and formal mathematics.

Remember
Character     ⋣
Unicode       U+22E3
Named entity  ⋣
Hex entity    ⋣
Decimal       ⋣
CSS escape    \22E3
Affirmative   ⊒ (⊒, U+2292)

Named, hex, decimal, CSS, and a typed character all produce the same glyph: ⋣. Prefer ⋣ in HTML source for clarity.

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Not Square Original Of Equal To (&nsqsupe;)</title>
  <style>
    #point::after {
      content: "\22E3";
    }
  </style>
</head>
<body>
  <p>Using Named Entity: &nsqsupe;</p>
  <p>Using Hex Code: &#x22E3;</p>
  <p>Using HTML Code: &#8931;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Example: a &nsqsupe; b</p>
</body>
</html>
Try It Yourself

How It Works

1. Named: &nsqsupe; is the clearest HTML form and renders ⋣.

2. Hex: U+22E3 → &#x22E3; in HTML. Same result as the named entity.

3. Decimal: same code point as 8931 → &#8931;. Same result as hex.

4. CSS: use \22E3 in content (not an HTML entity). #point::after appends that ⋣ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with this relation symbol.

Pair

&nsqsupe; ≠ &sqsupe;

&nsqsupe; is the negation. &sqsupe; is the affirmative square original of or equal (⊒).

Look-alikes

Not &nsqsube; or &ne;

&nsqsube; is the image-side negation (⋣ vs ⋢). &ne; is ordinary ≠ — a different operator.

CSS vs HTML

Do not mix escapes

\22E3 belongs in CSS. &nsqsupe; / &#x22E3; / &#8931; belong in HTML.

Fonts

Glyph coverage

Some fonts omit Mathematical Operators. If ⋣ looks like a box, switch to a math-capable font.

Encoding

Declare UTF-8

If you paste ⋣ directly, keep <meta charset="UTF-8"> so the file is not misread.

Semicolon

End references

Always finish with ; — write &nsqsupe;, not &nsqsupe.

Browser Support

Not square original of equal to (U+22E3) and its entity forms (&nsqsupe;, &#x22E3;, &#8931;, CSS \\22E3) are supported in all modern browsers. Glyph availability depends on the font.

✓ Universal encoding

Not Square Original Of Equal To (&nsqsupe;)

Encode with named, hex, decimal, or CSS escape — or paste ⋣ directly in UTF-8 HTML.

Bottom line: Prefer &nsqsupe; for readable HTML. Use \\22E3 only inside CSS content.

Key Takeaways

  • Unicode: this character is U+22E3 (decimal 8931).
  • HTML: prefer &nsqsupe; — or use &#x22E3; / &#8931;.
  • CSS: use \22E3 inside content for generated text.
  • Watch out: &nsqsupe; ≠ &sqsupe; ≠ &nsqsube; ≠ &ne;.

One line: U+22E3 → &nsqsupe; / &#x22E3; / &#8931; / CSS \22E3.

Frequently Asked Questions

Use &nsqsupe; (named), &#x22E3; (hex), &#8931; (decimal), or the CSS escape \22E3 in the content property. All render ⋣. Prefer &nsqsupe; in HTML source.
U+22E3 (NOT SQUARE ORIGINAL OF OR EQUAL TO). Hex 22E3, decimal 8931. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. &nsqsupe; is the HTML5 named entity for ⋣. Related: &sqsupe; for ⊒ (U+2292) and &nsqsube; for ⋢ (U+22E2).
Use it in order theory, relation algebra, and formal mathematics when you need to negate the square-original-of-or-equal relation (⊒). Prefer &nsqsupe; for readable source.
HTML entities (&nsqsupe;, &#8931;, or &#x22E3;) go in markup. The CSS escape \22E3 is used in stylesheets (usually in the content property of ::before/::after). Both render ⋣.
⊒ (&sqsupe;, U+2292) is the affirmative square original of or equal relation. ⋣ (&nsqsupe;) is its negation. ⋢ (&nsqsube;, U+22E2) is the image-side negation — opposite orientation.

Did you know?

Not square original of or equal to (⋣) is Unicode U+22E3 (decimal 8931) in Mathematical Operators. HTML5 provides &nsqsupe; — the most readable form. It negates square original of or equal to (&sqsupe;, ⊒, U+2292). The paired image-side negation is &nsqsube; (⋢, U+22E2).
