Unicode Version 17.0
𝘁
U+1D601 "𝘁" Mathematical Sans-Serif Bold Small T is a letter used primarily in mathematical and scientific notation to denote a variable, constant, or function in a sans-serif bold typeface. It belongs to the Mathematical Alphanumeric Symbols block, which provides distinct glyphs for letters to avoid confusion with ordinary text and to convey specific semantic meanings in formulas. When employed in documents or digital environments, this character allows authors to clearly indicate that the letter "t" represents a mathematical entity, such as time in physics or a parameter in statistics, rather than a plain text character.
