Hi list, When I run this test code \definefontfamily[trm][math][tex gyre termes math] \definefontfamily[pag][math][tex gyre pagella math] \definefontfamily[bon][math][tex gyre bonum math] \definefontfamily[sch][math][tex gyre schola math] \definefontfamily[stx][math][stix two math] \starttext \starttabulate[|c|c|] \FL \NC \bf Font name \NC \bf Math prime \NR \ML \NC Latin modern \NC \m{x'} \NR \NC Termes \NC \switchtobodyfont[trm] \m{x'} \NR \NC Pagella \NC \switchtobodyfont[pag] \m{x'} \NR \NC Bonum \NC \switchtobodyfont[bon] \m{x'} \NR \NC Schola \NC \switchtobodyfont[sch] \m{x'} \NR \NC Stix \NC \switchtobodyfont[stx] \m{x'} \NR \BL \stoptabulate \stoptext on my machine, the prime symbols are being placed too high (except for latin modern which is normal). Running the same code on the wiki gives the correct output though. Does anyone else get the same output? Screenshot attached. Jack
