Many thanks for this, Wolfgang. That is very helpful. Right now, then, I have:

\definefallbackfamily [mainface] [rm] [Brill] 
[tf=style:italic, range={0x03B8}, offset={0x03D1}]%Greek theta

[range={0x30-0x39}] %oldstyle numerals, normal

\definefallbackfamily [mainface] [mm] [Brill] [preset=math:lowercasenormal]
\definefallbackfamily [mainface] [mm] [BrillItalic] [preset=math:lowercaseitalic]

The font name for the third argument is *always* Brill and not BrillItalic or BrillBold.

\definefallbackfamily [mainface] [mm] [Brill] [preset=math:uppercasenormal]
\definefallbackfamily [mainface] [mm] [BrillItalic] [preset=math:uppercaseitalic]

\definefallbackfamily [mainface] [mm] [Brill] [preset=math:lowercasegreeknormal]
\definefallbackfamily [mainface] [mm] [BrillItalic] [preset=math:lowercasegreekitalic]
\definefallbackfamily [mainface] [mm] [Brill][preset=math:uppercasegreeknormal]
\definefallbackfamily [mainface] [mm] [BrillItalic] [preset=math:uppercasegreekitalic]

\definefontfamily[mainface][mm][TeX Gyre Termes Math][scale=0.94]

\setupmathematics[ucgreek=normal, lcgreek=italic]



normal: 1234567890\quad math: \m{1234567890}

normal: ABCDEFabcdef\quad italic: \emph{ABCDEFabcdef}\quad math: \m{\red ABCDEFabcdef}

normal: ΑΒΓΔΕΘαβγδεθ\quad slanted: \emph{ΑΒΓΔΕΘαβγδεθ}\quad math: \m{\red ΑΒΓΔΕΘαβγδεθ}

Greek theta: \emph{θ}


As you can see, all I need is to get the Brill lowercase Greek in mathmode and the proper slanted Greek theta.

\m{\theta \vartheta}

I have tried this with Pagella and Cambria instead of the Brill font and the problem persists. So I must be doing something wrong. But what?

Pagella and Cambria have a proper math font, why would you use fallbacks for them.
