Hi Mikael,

math is all Greek to me, but this seems to work (I guess, fallback
should beextended to actual character:

    \definefontfamily [mainface] [rm] [TeX Gyre Pagella]
    \definefallbackfamily [mainface] [mm] [TeX Gyre Pagella Math]
        [range={uppercasedoublestruck, 0x02102-0x02124}]
    \definefontfamily [mainface] [mm] [Neo Euler]
    \setupbodyfont[mainface,12pt]
    \starttext
    \startTEXpage[offset=3pt]
    Test: $\blackboard C$ or $\mathbb P$

    \switchtobodyfont[pagella]
    Test: $\blackboard C$ or $\mathbb P$
    \stopTEXpage
    \stoptext

Just in case it helps,

Pablo
