Bet symbol (ℶ) is Unicode U+2136 in the Letterlike Symbols block. In set theory it marks beth numbers (transfinite cardinals). HTML provides the named entity ℶ.
Remember
Character ℶ
Unicode U+2136
Hex entity ℶ
Decimal ℶ
Named entity ℶ
CSS escape \2136
Not the same ב U+05D1 (Hebrew letter bet)
All of these produce the same glyph: ℶ. Prefer ℶ in hand-written HTML; type ℶ in UTF-8 when you can; use numeric or CSS forms for generated content.
One page that shows ℶ with hex, decimal, named entity, CSS escape, and a typed character. Use View Output or open the live editor.
Hex + Decimal + Named + CSS + Typed
Five ways to produce ℶ in a single document.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

<style>

Bet symbol using Hex Code: ℶ
Bet symbol using HTML Code: ℶ
Bet symbol using Named Entity: ℶ
Bet symbol using CSS Entity: ℶ
Typed directly: ℶ
How It Works
1. Hex:U+2136 → ℶ in HTML. The browser turns it into ℶ.
2. Decimal: same code point as 8502 → ℶ. Same result as hex.
3. Named:ℶ is the standard HTML name for U+2136 — clear in source.
4. CSS: use \2136 in content (not an HTML entity). #point::after appends that ℶ after the paragraph text.
5. Typed ℶ: fine in UTF-8 source. All five lines show the same glyph.
Pitfalls & Tips
Common mistakes when working with bet symbol (ℶ).
ב
Not Hebrew letter bet
For Hebrew language text use ב (U+05D1). Reserve ℶ for math letterlike use.
Name
Entity is ℶ
The HTML name is ℶ (beth), not &bet;.
a11y
Say “beth”
Screen readers may not announce the symbol. Add a short label when meaning matters.
CSS vs HTML
Do not mix escapes
\2136 belongs in CSS. ℶ / ℶ belong in HTML.
Fonts
Use math-capable fonts
Some UI fonts omit Letterlike Symbols. Prefer fonts with solid math coverage.
Semicolon
End references
Always finish with ; — write ℶ, not &beth.
Compatibility
Browser Support
Bet symbol (U+2136) and its entity forms (ℶ, ℶ, ℶ, CSS \\2136) are supported in all mainstream browsers. Glyph availability depends on font support for Letterlike Symbols.

Bottom line: Prefer ℶ or a typed ℶ for normal text. Use numeric forms when generating markup, and \\2136 only inside CSS content.
Use ℶ (hex), ℶ (decimal), ℶ (named), or the CSS escape \2136 in the content property. All render ℶ. You can also paste ℶ directly if your file is UTF-8.
U+2136 (hex 2136, decimal 8502). Unicode names it BET SYMBOL. It belongs to the Letterlike Symbols block.
Yes. ℶ maps to U+2136. Prefer it in hand-written HTML; numeric forms are useful in generated markup.
ℶ (U+2136) is the math letterlike bet symbol (beth numbers). ב (U+05D1) is the Hebrew letter bet for language text. Use the code point that matches your meaning.
HTML entities (ℶ, ℶ, or ℶ) go in markup. The CSS escape \2136 is used in stylesheets (usually in the content property of ::before/::after). Both render ℶ.
In set theory and math notes for beth numbers (for example ℶ₀). Pair it with alef, gimel, or dalet symbols when comparing letterlike cardinals.
