These are not in the <Greek alphabet>:

Mathematical symbol that looks like a Greek letter but isn't

Nope, it is not a <Greek letter>, notably it is not a lowercase <delta>. It is just some random made up symbol that looks like a <letter D>. Which is of course derived from <delta>, which is why it is all so damn confusing.

I think the symbol is usually just read as "<D>" as in "d f d x" for $\pdv{F(x, y, z)}{x}$.
