The ▯ symbol, officially known as the White Vertical Rectangle, is a geometric shape used in various typographic and technical contexts. Often affectionately called a "tofu" block, it frequently appears as a fallback character when a device lacks the proper font to display a specific text or emoji. Beyond indicating missing characters, it is used in text-based UI design mockups as a placeholder for buttons, input fields, or empty checkboxes.
