The complete Letterlike Symbols block (U+2100–U+214F): approximately 80 characters that are letter-derived but carry distinct semantic meanings. Highlights include blackboard-bold capital letters used in mathematics (ℂ ℍ ℕ ℙ ℚ ℝ ℤ), script forms (ℒ ℛ ℰ ℱ), Fraktur letters (ℌ ℭ), the Planck constant (ℎ ℏ), and symbols with legal or scientific use: Celsius (℃), Fahrenheit (℉), numero (№), phonograph copyright (℗), service mark (℠), and trade mark (™). An essential block for mathematical typesetting and formal notation.
