What Is Square Original Of Or Equal To?

Square original of or equal to (⊒) is the Unicode character at U+2292 in Mathematical Operators. Official name: SQUARE ORIGINAL OF OR EQUAL TO. It is a square-style “original of or equal” / supseteq-like relation — the dual of ⊑.

Remember

Decimal       ⊒

Prefer ⊒ in HTML markup (⊒ and ⊒ are aliases). You can also type ⊒ in UTF-8, or use numeric forms when needed. For plain square original of, use ⊐ (⊐) instead.

How It Works

1. Named: &sqsupe; is the HTML5 name for U+2292 → ⊒. Best default in markup.

2. Hex: U+2292 → &#x2292; in HTML. Same glyph as the named form.

3. Decimal: same code point as 8850 → &#8850;. Same result as hex and named.

4. CSS: use \2292 in content (not an HTML entity). #point::after appends that ⊒ after the paragraph text.

5. Typed / notation: paste ⊒ in UTF-8, or write A &sqsupe; B for a short relation.

Pitfalls & Tips

Common mistakes when working with &sqsupe;.

vs ⊐

Not plain square original of

U+2290 (⊐, &sqsup;) is the basic relation. U+2292 adds the “or equal to” sense.

vs ⊇

Not ordinary supseteq

⊇ (U+2287, &supe;) is the common superset-or-equal symbol. U+2292 is the square-style form.

vs ⋥

Not the “not equal” form

⋥ (U+22E5) means square original of or not equal to — a different character with no named entity.

Name

Remember &sqsupe;

The named entity is &sqsupe; — not &supe; (that is U+2287) and not &sqsup; (U+2290).

CSS vs HTML

Do not mix escapes

\2292 belongs in CSS strings. &sqsupe; / &#x2292; / &#8850; belong in HTML.

Semicolon

End named entities

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

A11y

Name the relation in context

Screen readers may announce the symbol unevenly. Prefer nearby words like “square original of or equal to” when the glyph carries meaning alone.

Browser Support

Square original of or equal to (U+2292) and its entity forms (&sqsupe;, &#x2292;, &#8850;, CSS \\2292) are supported in all mainstream browsers. Visible glyphs depend on Mathematical Operators font coverage.

✓ Universal support

Square Original Of Or Equal To (&#x2292;)

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

Bottom line: Prefer &sqsupe; in HTML. Use &#x2292; / &#8850; when numeric form is required, and \\2292 only inside CSS content.

Key Takeaways

  • Unicode: this relation is U+2292 (decimal 8850) — glyph ⊒.
  • HTML: prefer &sqsupe; — also &#x2292; / &#8850; / type ⊒.
  • CSS: use \2292 inside content for generated text.
  • Meaning: ⊒ is “or equal” — not ⊐ (&sqsup;), not ⊇ (&supe;).

One line: U+2292 → &sqsupe; / &#x2292; / &#8850; / CSS \2292.

Frequently Asked Questions

Use &sqsupe; (named), &#x2292; (hex), &#8850; (decimal), type ⊒ directly in UTF-8, or the CSS escape \2292 in content. Prefer &sqsupe; in normal HTML.
U+2292 (SQUARE ORIGINAL OF OR EQUAL TO). Hex 2292, decimal 8850. It belongs to Mathematical Operators (U+2200–U+22FF).
Yes. Use &sqsupe; (aliases &SquareSupersetEqual; and &sqsupseteq;). Numeric forms &#8850; and &#x2292; also work.
No. ⊒ is U+2292 (&sqsupe;). ⊐ is U+2290 (&sqsup;). ⊇ is U+2287 (&supe;, superset of or equal to).
Use it for square-original-of-or-equal / square-supseteq-style notation in set theory and academic math — not as a substitute for ordinary ⊇.
HTML entities (&sqsupe;, &#8850;, or &#x2292;) go in markup. The CSS escape \2292 goes in stylesheet strings (usually content on ::before/::after).

Did you know?

Square original of or equal to is Unicode U+2292 (decimal 8850) — glyph ⊒ in Mathematical Operators (U+2200–U+22FF). HTML5 names it &sqsupe; (also &SquareSupersetEqual;, &sqsupseteq;). Official name: SQUARE ORIGINAL OF OR EQUAL TO. Do not confuse with square original of U+2290 (&sqsup;, ⊐) or superset of or equal to U+2287 (&supe;, ⊇).
