U+211B "ℛ" Script Capital R Unicode Character

Unicode Version 17.0

U+211B "ℛ" Script Capital R is a typographic symbol representing a stylized, handwritten uppercase R, often used in mathematical and scientific notation to denote the set of real numbers in blackboard bold contexts or as a general calligraphic letter in formal equations. It belongs to the Letterlike Symbols block of Unicode, which contains characters derived from ordinary letters but given specialized meanings in fields such as mathematics, physics, and logic. This character differs from ordinary roman R by its distinctive, flowing script form, and it can be confused visually with the similar blackboard bold symbol ℝ (U+211D), though ℛ maintains a more cursive appearance. Its inclusion in Unicode ensures consistent representation across digital platforms for technical documents and academic texts.
