Overview

Styling carries meaning in mathematics, and the Mathematical Alphanumeric Symbols block exists so that meaning survives in plain text. U+1D6B0 is capital iota in bold, encoded separately from ordinary Greek U+0399 precisely because the boldness is semantic rather than typographic — a vector or tensor named bold iota is not the same object as one named plain iota. Unicode gives it the general category Lu (letter, uppercase) and a compatibility decomposition back to U+0399, so NFKC normalisation collapses it and erases the distinction. That fallback is worth knowing before storing these characters in a field that normalises, since the mathematical content is lost even though the text still reads.
