ℤ
Double-struck capital Z
Blackboard-bold Z, the universal symbol for the set of integers (from German Zahlen, 'numbers'). Like the other number-set symbols it is encoded as its own character, so it can be used in plain text, filenames, and titles where math font styling is unavailable. Pairs with ℕ, ℝ, and ℚ.
