Mathematical Fraktur Capital D Symbol

𝔇 is the Mathematical Fraktur Capital D character used as a styled letter in math and technical text.

U+1D507

𝔇 (U+1D507) is a Unicode character from the Mathematical Fraktur block. It’s commonly used to represent a specifically styled capital β€œD” in mathematical or technical writing. You can copy it directly or use the provided HTML/CSS/JavaScript escapes.

Mathematical Fraktur Capital D Symbol Meaning

𝔇 is a β€œD” in the Mathematical Fraktur (script) style. Like other styled Unicode letters, its meaning is usually determined by context rather than a universal definition. In many documents, designers and authors use it to distinguish sets, operators, or named objects that must be visually different from a standard italic or plain β€œD”. For example, it can label a particular domain, a transformation, or a matrix/operator notation when the surrounding notation already uses other letter styles. When writing, pay attention to font support and consistencyβ€”different fonts may render the Fraktur style slightly differently.

Common uses

  • β€’Labeling a concept or variable as a styled capital D in math notes and worksheets
  • β€’Using as a distinctive operator/name in technical writing and diagrams
  • β€’Typing it in academic documents where a Fraktur letter style is required
  • β€’Creating consistent notation in presentations, reports, and math-heavy templates
  • β€’Designing typographic marks (e.g., a β€œD” monogram) in contexts that support Unicode math letters

What is the Unicode code point for 𝔇?

𝔇 is U+1D507 (Mathematical Fraktur Capital D).

Will 𝔇 look the same in all fonts?

Not always. Font support affects rendering, and Fraktur letters may vary slightly between fonts, even though the character is the same.
