One can also try to instead use the accent mechanism instead of a stacker: % engine=luatex \definemathtopaccent[widebar] ["0305] \startTEXpage[offset=3pt] $\overbar{OA}$ $\widebar{OA}$ \stopTEXpage The \widebar is defined (almost) like that in lmtx. /Mikael ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________
