The bold and italic symbols/letters aren’t a problem because the have their own unicode points but for the normal upright characters there should be proper key (like the lcgreek and ucgreek keys) which prevent ConTeXt to make them into italic characters. The \everymathematics hack works but isn’t very nice.

\setupmathematics[lcgreek=normal]

\setupbodyfont[cambria]

%\appendtoks \rm \to \everymathematics

\starttext

\m{Ξ±π›‚π›ΌπœΆ}

\m{D𝐃𝐷𝑫}

\m{{\rm D}𝐃𝐷𝑫}

\stoptext
