Definition

What Is the Multiset Entity?

Multiset (⊌) is the mathematical multiset symbol at Unicode U+228C. It is used in set theory for bag/multiset notation. There is no named HTML entity for it.

Remember

Character     ⊌
Unicode       U+228C
Hex entity    &#x228C;
Decimal       &#8844;
CSS escape    \228C
Named entity  (none)

Hex, decimal, CSS, and a typed character all produce the same glyph: ⊌.

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Direct character	`⊌`	UTF-8 HTML text (default choice)
Hex entity	`⊌`	HTML markup
Decimal entity	`⊌`	HTML markup
CSS escape	`\228C`	Stylesheet `content`
Named entity	—	Not defined in HTML5

When to Use Which

Situation	Use
Multiset / bag notation in math	Type `⊌` (UTF-8) or `⊌`
Need an entity in HTML source	`⊌` or `⊌`
Generated text via `::before` / `::after`	`content: "\228C"`
Multiset multiplication (⊍)	See Multiset Multiplication
C++ / programming containers	Write code — do not use this math entity

Hex + Decimal + CSS + Typed

Four ways to produce ⊌ in a single document.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Multiset (⊌)</title>
  <style>
    #point::after {
      content: "\228C";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x228C;</p>
  <p>Using HTML Code: &#8844;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Multiset: A ⊌ B</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+228C → ⊌ in HTML. The browser turns it into ⊌.

2. Decimal: same code point as 8844 → ⊌. Same result as hex.

3. CSS: use \228C in content (not an HTML entity). #point::after appends that ⊌ after the paragraph text.

4. Meaning: ⊌ is multiset notation in math — not a programming container, and not ordinary subset ⊂.

Pitfalls & Tips

Common mistakes when working with Multiset.

Named?

No named entity

HTML5 does not define a named entity for U+228C. Use numeric forms.

Meaning

Math, not C++

This entity is a Unicode operator — not std::multiset or any runtime container.

Pair with ⊍ / ⊎

Multiset Multiplication (⊍) and Multiset Union (⊎) are related operators in the same family.

CSS vs HTML

Do not mix escapes

\228C belongs in CSS. ⊌ / ⊌ belong in HTML.

Encoding

Declare UTF-8

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

Semicolon

End references

Always finish with ; — write ⊌, not &#8844.

Compatibility

Browser Support

Multiset (U+228C) and its numeric entity forms (⊌, ⊌, CSS \\228C) are supported in all mainstream browsers with a Unicode-capable font.

✓ Universal support

Multiset (⊌)

Type ⊌, or encode with hex, decimal, or CSS escape — same glyph everywhere fonts support it.

100% Browser coverage

Google Chrome Supported

Yes

Microsoft Edge Supported

Yes

Mozilla Firefox Supported

Yes

Apple Safari Supported

Yes

Opera Supported

Yes

Internet Explorer IE 9+

Yes*

U+228C / entities Full support

Bottom line: Type ⊌ for normal UTF-8 text. Prefer ⊌ or ⊌ when encoding must be explicit, and \\228C only inside CSS content.

Remember

Key Takeaways

Unicode: Multiset is U+228C (decimal 8844).
HTML: use ⊌ or ⊌ — no named entity.
CSS: use \228C inside content for generated text.
Meaning: math bag notation — not a programming multiset.

One line: U+228C → type ⊌, or encode as ⊌ / ⊌ / CSS \228C.

Frequently Asked Questions

How do I display the Multiset symbol in HTML using entities?

Use ⊌ (hex), ⊌ (decimal), or the CSS escape \228C in the content property. All render ⊌. There is no named HTML entity for U+228C.

What is the Unicode value for Multiset?

U+228C (MULTISET). Hex 228C, decimal 8844. It belongs to the Mathematical Operators block.

Is there a named HTML entity for U+228C?

No. U+228C has no named HTML entity. Use numeric references like ⊌ or ⊌.

When should I use this HTML entity?

Use it in set theory and combinatorics for multiset (bag) notation — for example A ⊌ B in formal math content.

What is the difference between HTML code and CSS entity for U+228C?

HTML entities (⊌ or ⊌) go in markup. The CSS escape \228C is used in stylesheets (usually in the content property of ::before/::after). Both render ⊌.

Is Multiset the same as C++ std::multiset?

No. U+228C is a Unicode mathematical symbol. It does not implement or represent a programming container.

Did you know?

Multiset is Unicode U+228C (decimal 8844) — MULTISET in Mathematical Operators. HTML5 has no named entity — use ⊌ or ⊌. It is a math symbol for bag/multiset notation — not C++ std::multiset. Related: Multiset Multiplication ⊍ and Multiset Union ⊎.
