Do you know a (free) math font with proper math kerns? I made a fast search through the lua files of my font cache but couldn't find anything saying "mathkern". -- Ulrike Fischer http://www.troubleshooting-tex.de/ ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

The usual 'math italic mess' where fonts assume italic correction
instead of proper math kerns.
I'll add a fix for that. We already have \mathscriptcharmode (default 1)
for lists and will have \mathboxcharmode (also defaulting to 1) for
loose chars. We can turn it off in order to investigate issues with real
math kerns (which most fonts seem to lack). Depending on how fonts
develop We might need a font bound flag too.
(In context i might turn these italics into proper math kerns some day.)
