U+1D42D "𝐭" Mathematical Bold Small T Unicode Character
Unicode Version 17.0
𝐭
U+1D42D "𝐭" Mathematical Bold Small T is part of the Mathematical Alphanumeric Symbols block, designed to represent the Latin letter 't' in a bold typeface for use in mathematical and scientific notation. It allows authors to distinguish variables, constants, or terms from standard text, particularly in contexts where a bold weight indicates a vector, matrix, or other special mathematical object. This character was introduced in Unicode version 3.1, released in 2001, and is encoded for interoperability across digital platforms, ensuring that mathematical expressions render consistently in documents, web pages, and software applications.
