What 𝖽 means
It is Latin lowercase d in a mathematical sans-serif style.
The mathematical alphabet reuses Latin letters in styles that let formulas mark distinct symbols or roles; this math d has no fixed value without its surrounding notation. Unicode identifies the sans-serif math style, while each font supplies its own drawing.
Should I use 𝖽 in ordinary text?
Usually, no.
Mathematical alphanumeric letters are intended for mathematical or technical notation, where the style can carry meaning. For a sans-serif sentence, use ordinary letters with text formatting instead.
Mathematical or technical; the sans-serif style can distinguish this letter inside a formula.
