Symbols for Terminal & CLI

Modern CLI tools use Unicode to create polished terminal interfaces: box-drawing characters build table borders and panels, block elements render progress bars and sparklines, and checkmarks or crosses indicate task status. This reference covers the box drawing, block element, and Braille pattern ranges used by popular CLI frameworks like Rich, Ink, and Charm, along with the arrows and status symbols that make terminal output scannable. All characters are tested for rendering in common terminal emulators on macOS, Linux, and Windows Terminal.
