U+1D57F "𝕿" Mathematical Bold Fraktur Capital T Unicode Character
Unicode Version 17.0
𝕿
U+1D57F "𝕿" Mathematical Bold Fraktur Capital T is a typographic symbol belonging to the Mathematical Alphanumeric Symbols block, designed for use in mathematical and scholarly texts where a bold, blackletter style is needed. It represents a bold variation of the Fraktur or Gothic script, which historically appears in old German manuscripts and mathematical notation for concepts like transfinite numbers or tensor spaces. This character is distinct from the regular Latin capital T, as its ornate, thick strokes and angular flourishes help it serve as a specialized glyph in formal mathematical typesetting.
