Meaning and usage
The Unicode character ⋿ is named z notation bag membership and is used as a specialized mathematical sign in contexts where its exact shape carries meaning.
Use ⋿ only when the source or field defines this exact symbol. For Z Notation Bag Membership (⋿), in portable equation source, keep the character or an equivalent LaTeX command together with a written definition because visually similar signs can represent different relations or operators.

Formula examples
A ⋿ Bx ⋿ yHow to type Z Notation Bag Membership
- Windows
- Open Character Map or enter Unicode 22FF in a Unicode-aware application.
- macOS
- Open Character Viewer and search for z notation bag membership.
- Microsoft Word
- Type 22FF, then press Alt+X in Word where supported.
- iPhone and iPad
- Copy and paste ⋿, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ⋿, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ⋿ or use Insert → Special characters. For structured math, use the equation editor and verify ⋿.
- Excel
- Paste ⋿ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- State the set-theory convention around ⋿; Use ⋿ only when the source or field defines this exact symbol. For Z Notation Bag Membership (⋿), in portable equation source, keep the character or an equivalent LaTeX command together with a written definition because visually similar signs can represent different relations or operators.
- For plain text, copy ⋿ as U+22FF; for structured equations, use ⋿ in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Z Notation Bag Membership.
When to use ⋿
- Use ⋿ in plain text when a Unicode character is appropriate and the destination preserves U+22FF.
- Use ⋿ in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Z Notation Bag Membership is used in discrete math, set theory with a field-specific convention.
