What 𝘦 means
The formula's author decides what it represents.
Math notation uses letter styles to keep symbols distinct, so 𝘦 can mark a different variable from plain e or serif italic 𝑒.
Why is this e encoded separately?
Its style can carry meaning in equations.
By 1999, science publishers used styled math alphabets. A science-publishing project called STIX proposed complete encoded sets so plain text could preserve distinct symbols. These sets extended an older special-letter collection. Unicode recommends text formatting for stylized prose.
