Hi Pol,

You can use the following:

%% begin show-math.tex
\doifmode{mkiv}{\usemodule[s][mat-11]}
\starttext
\doifmodeelse{mkiv}{\showmathfontcharacters}{\showmathcharacters}
\stoptext
%% end show-math.tex

However in mkiv the presentation of math fonts is not the same as in mkii.
I don't know how to get the mkii presentation of the math fonts in mkiv…

Best regards: OK
