Double-Struck Capital R is a letterlike symbol — a character shaped like an ordinary letter but assigned a specific technical, legal, or scientific meaning distinct from the plain alphabet letter it resembles.
Unicode block: Letterlike Symbols (U+2100–U+214F). This block gathers symbols that look like letters but carry a special technical meaning — units (like ℃), mathematical sets (like ℝ for real numbers), and legal/trademark marks — that needed their own distinct Unicode identity.
At Unicode code point U+211D (decimal 8477), Double-Struck Capital R is the 30th of 80 characters cataloged in this category on How To Type Any Symbol. In terms of typing methods, like most characters outside the 0–255 legacy codepage range, it has no dedicated Alt-code or single-key shortcut on Windows or Mac, so copy-paste is the standard, universal method for typing it. Regardless of platform, clicking the copy button above places the exact character on your clipboard, ready to paste into any application that accepts Unicode text.
💡 Good to know: Most of these symbols have dedicated LaTeX commands for technical typesetting, which is often more reliable than copy-paste for long documents.
