Unicode Version 17.0
𝟺
U+1D7FA "𝟺" Mathematical Monospace Digit Four is part of the Mathematical Alphanumeric Symbols block and belongs to a set of digits designed for use in mathematical and technical contexts where a fixed width, typewriter style is required. It visually resembles the standard digit four but is rendered in a monospace font, ensuring consistent horizontal spacing in plain text environments. This character allows authors to distinguish between ordinary digits and digits used as mathematical variables or within code-like notations, avoiding ambiguity in academic papers, programming documentation, and digital typesetting.
