U+1D63_rᵣᵣ<mi>ᵣ</mi>Semantic identity and intent
Characters to distinguish
- ² — Superscript Two
- ₁ — Subscript One
- ⁰ — Superscript Zero
Use ᵣ in the right format
Meaning and usage
Represents subscript r as a standalone Unicode character for compact linear notation.
Use ᵣ only when a plain-text destination cannot render structured subscripts or superscripts; use LaTeX _r for full equations.
Pronunciation: subscript r
Formula examples
ᵣ is used in a context where represents subscript r as a standalone Unicode character for compact linear notation.How to type Subscript R
- Windows
- Use Character Map or enter U+1D63 in a Unicode-aware application.
- macOS
- Open Character Viewer with Control–Command–Space and search by the symbol name.
- Microsoft Word
- In an equation, type _r and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste ᵣ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ᵣ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ᵣ or use Insert → Special characters. For structured math, use the equation editor and verify _r.
- Excel
- Paste ᵣ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Do not substitute a visually similar Latin or differently styled character for ᵣ; case and mathematical alphabet style can identify different quantities.
- For plain text, copy ᵣ as U+1D63; for structured equations, use _r in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Subscript R.
When to use ᵣ
- Use ᵣ in plain text when a Unicode character is appropriate and the destination preserves U+1D63.
- Use _r in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Subscript R is used in super sub, math alphanumeric with a field-specific convention.
