That looks like A7AC LATIN CAPITAL LETTER SCRIPT G, to me.

> I didn't find it in Unicode, but it's maybe in the DAM2 draft repertoire (n4380), as *+A7AC LATIN CAPITAL LETTER SCRIPT G proposed by Michael Everson in n4030 “Proposal for the addition of five Latin characters to the UCS”, because he needed an upper case conterpart to U+0261 ɡ LATIN SMALL LETTER SCRIPT G for his “Ælɪsɪz Ədˈventʃəz ɪn ˈWʌndəlænd” book. This example is obviously totally different, and too late to have any influence on the encoding, but I think it might interest some reader of this list.

I don't see how it would "influence the encoding". It's just more evidence of use in a different context.

If one compares the green g's, the distinction between g U+0067 LATIN SMALL LETTER G and ɡ U+0261 LATIN SMALL LETTER SCRIPT G is clearly a glyph/font property in this text, as the gⁱ in the text and the ɡⁱ in the equation just below below correspond to the same physical quantity. This character could therefore be a * LATIN CAPITAL LETTER SMALL G, a kind of symmetric character to ɢ U+0262 LATIN LETTER SMALL CAPITAL G.

The small capitals have independent existence in linguistics, but I would be very surprised to find mathematicians making that distinction. More likely the G and D are capitals.
