What Is Double Struck / Blackboard Bold?

Double struck characters originate from blackboard bold — a style developed in mathematics classrooms where professors would draw bold letters on blackboards by making two parallel strokes instead of one filled stroke. The result is a letter with a distinctive doubled vertical line.

These characters come from the Mathematical Double-Struck block (U+1D538–U+1D56B) and include some well-known standalone symbols:

• ℝ — Real numbers
• ℤ — Integers (from German Zahlen)
• ℕ — Natural numbers
• ℂ — Complex numbers
• ℚ — Rational numbers
• ℙ — Primes (or projective space)
• ℍ — Quaternions
• ℤ — Integers
