Unicode Version 17.0

𝛳

U+1D6F3 "𝛳" Mathematical Italic Capital Theta Symbol is a typographic variant of the Greek capital letter theta, specifically designed for use in mathematical and scientific notation where italicized symbols help distinguish variables from ordinary text. It belongs to the Mathematical Alphanumeric Symbols block, which provides separate italic, bold, and script forms for common letters to avoid ambiguity in formulas. This character is typically rendered in a slanted italic style, making it suitable for representing angles, unknown parameters, or special mathematical functions in contexts such as calculus, geometry, and physics. It should not be confused with the standard Greek theta (Θ) or other styled variants, as its purpose is solely to maintain consistent formatting within technical documents.
