What 𝗈 means
Its style can mark a distinct symbol.
A formula may give differently styled letters different roles; this glyph has no fixed value on its own.
It was already used in scientific publishing by 1999. That year, the STIX science-publishing project proposed separate math-letter codes to keep formula distinctions in plain text.
In technical formulas, its sans-serif style can distinguish a symbol.
Use plain o in prose unless you mean the mathematical character.

1Can software turn 𝗈 into plain o?
Yes. Unicode's NFKC form, a compatibility cleanup, maps mathematical letters to plain base letters, erasing this style distinction.
