About double-struck letters

Also called blackboard bold. Maths teachers doubled one stroke of each letter on the chalkboard so โ„ (the real numbers) and โ„ค (the integers) stood apart from ordinary letters. Unicode has a double-struck character for every letter and digit, so the style keeps its look wherever you paste it, with no font installed.

  • Discord and WhatsApp
  • Word and Google Docs
  • Facebook names, which only allow plain letters
  • Accents like รฉ and รฑ are added as a separate mark, which some apps place slightly off

Double-struck fonts, also known as blackboard bold, are a typographic style often used in mathematics, logic, and scientific writing to distinguish sets and number systems such as โ„, โ„ค, and โ„š. Originating from chalkboard practices where teachers emphasized letters with multiple strokes, this style later became standardized in Unicode, ensuring cross-platform compatibility. Today, double-struck characters are essential for academic texts, coding languages, and digital documents where precision and clarity of meaning are required.
