What You'll Learn

How to display the Dalet symbol (ℸ) in HTML using named, hexadecimal, decimal, and CSS entity methods. The Dalet symbol is U+2138 in the Letterlike Symbols block (U+2100–U+214F)—the letterlike or mathematical form of the Hebrew letter Dalet, used in mathematics, symbolism, and Hebrew-related notation.

This character can be rendered with the named entity ℸ, hexadecimal ℸ, decimal ℸ, or CSS escape \2138. Do not confuse with the Hebrew script letter Dalet (ד, U+05D3).

🧠 How It Works

1

Named HTML Entity

&daleth; is the semantic named entity for the Dalet symbol—the easiest to read in source HTML.

HTML markup
2

Hexadecimal Code

&#x2138; uses the Unicode hexadecimal value 2138. The x prefix indicates hexadecimal format.

HTML markup
3

Decimal HTML Code

&#8504; uses the decimal Unicode value 8504 to display the same character.

4

CSS Entity

\2138 is used in CSS stylesheets, particularly in the content property of ::before and ::after.

CSS stylesheet
=

Same visual result

All four methods produce the Dalet symbol: ℸ. Unicode U+2138 is in Letterlike Symbols. For Hebrew script Dalet use &#x05D3; (ד).

💡 Best Practices

Do

  • Use &daleth; for readable source markup
  • Use ℸ (U+2138) for letterlike/math contexts
  • Use ד (U+05D3) for actual Hebrew text
  • Choose fonts with Letterlike Symbols coverage
  • Use \2138 only inside CSS content

Don’t

  • Confuse ℸ (letterlike) with ד (Hebrew script Dalet)
  • Assume all fonts render ℸ identically
  • Put CSS escape \2138 in HTML text nodes
  • Use HTML entities in JS (use \u2138 instead)
  • Mix entity styles randomly in one file
