The double horizontal box drawing character (═) is a legacy computing symbol used to create double-lined borders in text-based user interfaces. Originating from early DOS code pages, it pairs with other box-drawing characters to form tables, frames, and grids directly within terminal windows. Today, it remains popular among developers for building command-line tools, formatting plaintext documents, and crafting retro ASCII art.
