How to type Beth Symbol

Windows
Use Character Map and search for Beth Symbol, or paste the Unicode character (U+2136).
macOS
Open Character Viewer with Control–Command–Space and search for Beth Symbol.
Microsoft Word
In an equation, type \beth and press Space when Word supports the command; otherwise insert the Unicode character.
iPhone and iPad
Copy and paste ℶ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
Android
Copy and paste ℶ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
Google Docs
For plain text, paste ℶ or use Insert → Special characters. For structured math, use the equation editor and verify \beth.
Excel
Paste ℶ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.

Common mistakes

  • Do not reuse ℶ as an unrelated variable when it denotes Beth Symbol; define any nonstandard meaning explicitly.
  • For plain text, copy ℶ as U+2136; for structured equations, use \beth in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Beth Symbol.

When to use ℶ

  • Use ℶ in plain text when a Unicode character is appropriate and the destination preserves U+2136.
  • Use \beth in an equation editor when mathematical spacing or structure matters.
  • Define the local meaning when Beth Symbol is used in number sets, number theory with a field-specific convention.

Look-alikes and related characters
