x211C

x211C is the hexadecimal designation for the Unicode code point U+211C, which encodes the character SCRIPT CAPITAL R (ℜ). It is part of the Letterlike Symbols block. The glyph appears as a stylized, calligraphic capital R and is used in typography and mathematics as a decorative variant of the letter R.

In mathematics, ℜ is sometimes used to denote the real part of a complex number, though its usage varies by author and font. The more common symbol for the real numbers themselves is ℝ (U+211D), a different character in the same general family of symbols. Whether ℜ appears in a given document depends on font support and the encoding used.

Encoding and rendering: U+211C is supported in most modern Unicode fonts. In UTF-8, it is encoded as a three-byte sequence. In HTML, the character can be included with the numeric character reference ℜ in environments that support the font, though there is no universally standardized named HTML entity for this character.

Related symbols and notes: ℜ is one of several stylized R variants available in Unicode; it should not be confused with ℝ, which is commonly used to denote the real numbers. The broader Unicode Letterlike Symbols block contains other decorative and specialized letters that appear in mathematical and scientific notation, providing a range of options for typographic styling in technical texts.
