Hi Riobard,

Since math is done differently in mkiv than in mkii, indeed \showmathcharacters does not work in mkiv.
However one can get all the math characters in mkiv in a big list doing the following:

%%%% begin showmath.tex
\doifmode{mkiv}{\usemodule[fnt-25]}
\starttext
\doifmodeelse{mkiv}{\showmathfontcharacters}{\showmathcharacters}
\stoptext
%%%% end showmath.tex

Then, if using mkiv, in the resulting PDF file you can see all characters used in mathmode.

Best regards: OK
