How It Works
1. Named:ℸ is the HTML5 name for U+2138 → ℸ. Best default in markup.
2. Hex:U+2138 → ℸ in HTML. Same glyph as the named form.
3. Decimal: same code point as 8504 → ℸ. Same result as hex and named.
4. CSS: use \2138 in content (not an HTML entity). #point::after appends that ℸ after the paragraph text.
5. Typed: in a UTF-8 page you can paste ℸ directly. All five lines show the same glyph.
Pitfalls & Tips
Common mistakes when working with Dalet Symbol.
Hebrew
Not Hebrew letter dalet
ד (U+05D3) is for Hebrew text. ℸ is the letterlike math symbol.
Name
Spelling: daleth
The named entity is ℸ (with th). There is no &dalet; in HTML5.
Fonts
Letterlike font coverage
Some fonts omit U+2138. Prefer a font with Letterlike Symbols coverage for display.
CSS vs HTML
Do not mix escapes
\2138 belongs in CSS strings. ℸ / ℸ / ℸ belong in HTML.
Series
Alef → Bet → Gimel → Dalet
U+2135–U+2138 are related letterlike symbols. Pick the code point that matches the notation you need.
Semicolon
End references
Always finish with ; — write ℸ, not &daleth.
