What 𝖼 means
It marks a sans-serif mathematical letter.
The 1999 Unicode proposal targeted scientific and mathematical publishing: separate alphabets let plain text preserve distinct variables. They extend older letterlike symbols; 𝖼 adds a sans-serif c, not a fixed value.
Intended for math; plain-text styling is a side use.
