𞺱

U+1EEB1 "𞺱" Arabic Mathematical Double-Struck Sad is a specialized typographic symbol used primarily in mathematical and scientific notation to represent the Arabic letter Sad in a double struck or blackboard bold style. This character belongs to the Arabic Mathematical Alphabetic Symbols block, which was designed to support the typesetting of mathematical expressions where Arabic script is used, often in contexts like academic papers or textbooks involving algebra, number theory, or logic. Its visual appearance mimics the familiar double struck characters found in Latin mathematical notation, but it retains the distinct form of the Arabic letter Sad, which corresponds to the sound similar to the English "s" and is the fourteenth letter of the Arabic alphabet.
