Not more than 3 years ago the addition of \usemodule[math-10] solved the Undefined control sequence error for \showmathfontcharacters. But at least in ConTeXt ver: 2016.07.23 13:35 this problem cropped up again. Where is \showmathfontcharacters defined nowadays? Hans van der Meer

When that macro is defined in s-mat-10.mkiv as \unexpanded\def\showmathfontcharacters {\dodoubleempty\doshowmathfontcharacters}

Add \usemodule[math-10] to your document.
