What 𝙹 means
It is a mathematical J whose style can distinguish it. An equation supplies its value; the letter has no universal one. Unicode expanded mathematical alphabets so equations could preserve letter-style distinctions in plain text. Some earlier forms sat in its Letterlike Symbols group, a set of letter-shaped signs. Fonts supply the glyph, so its appearance can vary.
