Overview

Double-struck letters, also called blackboard bold, arose from the practice of writing bold characters on a chalkboard by doubling their strokes, and the notation persisted into print for number sets and similar objects. U+1D552 is the lowercase a in that style, drawn from Mathematical Alphanumeric Symbols. A handful of double-struck capitals were encoded much earlier in the Letterlike Symbols block, so the alphabet is split across two ranges rather than being contiguous — a common consequence of Unicode encoding characters as needs arose. The general category is Ll (letter, lowercase), with a compatibility decomposition to ordinary a.
