Let me try again with fonts in the ConteXt distribution. The aim is to substitute Pagella letters (roman and Greek) and numerals for those in Dejavu Math. It gets the numerals and the Greek capitals right but the rest (roman lower– and uppercase, and lowercase Greek) are still in Dejavu. How can I fix this? \definefontfamily[mainface][serif][TeX Gyre Pagella][] \definefallbackfamily[mainface][mm][TeX Gyre Pagella] [range={0030-0039, 0041-005A, 0061-0071, 0391-03A9, 03B1-03C9}, scale=1] \definefallbackfamily [mainface] [mm] [TeXGyrePagella][preset=math:lowercasegreeknormal] \definefallbackfamily [mainface] [mm] [TeXGyrePagellaItalic] [preset=math:lowercasegreekitalic] \definefallbackfamily [mainface] [mm] [TeXGyrePagella] [preset=math:uppercasegreeknormal] \definefallbackfamily [mainface] [mm] [TeXGyrePagellaItalic] [preset=math:uppercasegreekitalic] \definefontfamily[mainface][mm][Dejavu Math][scale=1] \setupmathematics[autopunctuation={all}, ucgreek=normal, lcgreek=italic] \setupbodyfont[mainface,10pt] \starttext A~B~C~a~b~c (Pagella) \emph{A~B~C~a~b~c} (Pagella)\\ \m{A~B~C~a~b~c} (math: Pagella?) \blank 0123456789 (Pagella) \\ \m{0123456789} (math: Pagella?) \blank δ \emph{δ} (Pagella) \\ \m{δ} (math: Pagella?) \blank π \emph{π} (Pagella) \\ \m{π} (math: Pagella?) \blank Π \emph{ Π} (Pagella) \\ \m{Π} (math: Pagella?) \blank Δ \emph{ Δ} (Pagella) \\ \m{Δ} (math: Pagella?) \stoptext Alan On Tue, Sep 5, 2017 at 5:42 PM, Alan Bowen wrote:

I should like to have the Brill font substitute for the Greek alphabet (upper and lower cases) as well for the numerals in Tex Gyre Termes Math.

So far, I have been able to get the Brill numerals (oldstyle) but nothing more: the Greek letters in math mode are from Termes Math.

Here is what I have:

\definefontfamily[mainface][serif][Brill] [protrusion=quality, expansion=quality, mode=node, force=yes, ]

\definefallbackfamily[mainface][mm][Brill][range={0030-0039, 0391-03A9, 03B1-03C9}, scale=1]

\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[autopunctuation={all}, ucgreek=normal, lcgreek=italic]

\setupbodyfont[mainface,10pt]

\starttext

Any suggestions or pointers will be most welcome.
