How It Works
1. Named:ℛ is the HTML5 name for U+211B → ℛ (case-sensitive). ℛ is an alternate name for the same glyph.
2. Hex:ℛ inserts the same code point. Same visual as named.
3. Decimal:ℛ is the base-10 form of U+211B.
4. CSS: use \211B in content (not an HTML entity). #point::after appends that glyph after the paragraph text.
5. Typed: paste ℛ in a UTF-8 document, or write math text with ℛ.
Pitfalls & Tips
Common mistakes when working with this character.
Named
Prefer ℛ
The name is case-sensitive. ℛ and ℛ both render ℛ. Prefer ℛ for shorter, clearer source.
Look-alikes
Not ℜ and not plain R
Script capital R is ℛ (U+211B). Plain Latin is R. Black-letter / real-part is ℜ (U+211C). Match the notation you need.
Semantics
Prefer the letterlike symbol
Prefer U+211B (or ℛ) over styling a plain R with a script font when the semantics require the letterlike symbol.
Fonts
Check Letterlike coverage
Some fonts omit U+211B. If the glyph is missing, switch to a font with Letterlike Symbols support.
CSS vs HTML
Do not mix escapes
\211B belongs in CSS. ℛ / ℛ / ℛ belong in HTML.
Semicolon
End references
Always finish with ; — write ℛ, not &Rscr.
