The command set the fonts which are shown in the document but you still need the \showmathfontrepertoire command to generate the pages.10. Oktober 2016 um 18:07Put at front of the test document
\usemodule[math-repertoire]
\setupbodyfont[modern,12pt]
Observations:
(1) \showmathcharacterssetbodyfonts{modern}
No output
1. You’re mixing keywords and assignments.(2) \showmathfontcharacters[alternative=,option=,modern]}
Breaking off after page 2067 with a TeX error "Too many }'s"?
If there are still problems send complete examples.(3) \showmathfontrepertoire
2067 pages output, one character a page
So about (1) and (2) I do not understand what happens.
