Black-letter capital Z (ℨ) is Unicode U+2128 in the Letterlike Symbols block. It is the Fraktur / black-letter form of capital Z — used in math and gothic typography. HTML provides the named entities ℨ and ℨ.
Remember
Character ℨ
Unicode U+2128
Hex entity ℨ
Decimal ℨ
Named entity ℨ (also ℨ)
CSS escape \2128
Not the same Z (Latin) · ℤ U+2124 (double-struck)
All of these produce the same glyph: ℨ. Prefer ℨ in hand-written HTML; type ℨ in UTF-8 when you can; use numeric or CSS forms for generated content.

How It Works
1. Hex:U+2128 → ℨ in HTML. The browser turns it into ℨ.
2. Decimal: same code point as 8488 → ℨ. Same result as hex.
3. Named:ℨ (or ℨ) is the standard HTML name for U+2128 — clear in source.
4. CSS: use \2128 in content (not an HTML entity). #point::after appends that ℨ after the paragraph text.
5. Typed ℨ: fine in UTF-8 source. All five lines show the same glyph.
Pitfalls & Tips
Common mistakes when working with black-letter capital Z (ℨ).
Z
Not Latin Z
Ordinary text should use Latin Z. Reserve ℨ for Fraktur / letterlike use.
ℤ
Not double-struck Z
ℤ (U+2124) is double-struck capital Z, often used for the set of integers — a different code point.

Announce Fraktur Z
Screen readers may say “Z” or skip the glyph. Add visible or visually hidden context when meaning matters.
Fonts
Check letterlike coverage
Some UI fonts omit U+2128. Prefer fonts with solid Letterlike Symbols / Fraktur support.
CSS vs HTML
Do not mix escapes
\2128 belongs in CSS. ℨ / ℨ belong in HTML.
Semicolon
End references
Always finish with ; — write ℨ, not &Zfr.
Compatibility
Browser Support
Black-letter capital Z (U+2128) and its entity forms (ℨ, ℨ, ℨ, ℨ, CSS \\2128) are supported in all mainstream browsers. Glyph quality depends on font support for Letterlike Symbols / Fraktur.

Bottom line: Prefer ℨ or a typed ℨ for Fraktur Z. Use numeric forms when generating markup, and \\2128 only inside CSS content.

Key Takeaways
Unicode: black-letter capital Z is U+2128 (decimal 8488).
HTML: prefer ℨ (or ℨ / ℨ).
CSS: use \2128 inside content for generated text.
Watch out: ℨ ≠ Z ≠ ℤ (Fraktur ≠ Latin ≠ double-struck).
Use ℨ (hex), ℨ (decimal), ℨ or ℨ (named), or the CSS escape \2128 in the content property. All render ℨ. You can also paste ℨ directly if your file is UTF-8.
U+2128 (hex 2128, decimal 8488). Unicode names it BLACK-LETTER CAPITAL Z. It belongs to the Letterlike Symbols block.
Yes. ℨ and ℨ both map to U+2128. Prefer ℨ in hand-written HTML; numeric forms are useful in generated markup.
ℨ (U+2128) is Fraktur / black-letter capital Z. Ordinary Z is Latin capital Z (U+005A). ℤ (U+2124) is double-struck capital Z, often used for the integers.
HTML entities (ℨ, ℨ, or ℨ) go in markup. The CSS escape \2128 is used in stylesheets (usually in the content property of ::before/::after). Both render ℨ.
Use ℨ in math or typography when you need Fraktur Z (for example some Lie-algebra notation). For normal words, use Latin Z. Pair the glyph with a text label when accessibility matters.
