U+1EEA3 "𞺣" Arabic Mathematical Double-Struck Dal Unicode Character

U+1EEA3 "𞺣" Arabic Mathematical Double-Struck Dal is a specialized glyph from the Arabic Mathematical Alphabetic Symbols block, designed for use in scientific and mathematical contexts where letters are styled with a double-struck (blackboard bold) appearance. It specifically represents the Arabic letter Dal, which corresponds to the sound /d/, rendered in a bold, outline like form to denote sets, number systems, or other abstract mathematical entities. This character allows mathematicians and researchers working with Arabic script notation to maintain visual consistency with Latin double struck letters such as ℕ or ℝ, while supporting the distinct orthographic needs of Arabic based mathematical expressions.
