U+1D433 "𝐳" Mathematical Bold Small Z Unicode Character
Unicode Version 17.0
𝐳
U+1D433 "𝐳" Mathematical Bold Small Z is part of the Mathematical Alphanumeric Symbols block, designed for use in mathematical and scientific notation where a bold lowercase Latin letter is required to represent vectors, matrices, or specific variables. It is visually identical to a bold "z" in a standard serif typeface but is encoded separately from the regular bold "z" to preserve its distinct mathematical meaning and prevent font confusion in plain text. This character is typically used in academic contexts such as denoting the z-axis, a complex number variable, or a statistical z-score, ensuring consistent rendering across different platforms and software.
