Hi Hans, hi Taco, hi all, testing math with the latest ConTeXt beta i found some problems. My test file is: \usetypescriptfile[type-buy] \def\currentfontname {\ctxlua{tex.print(font.getfont(font.current()).fullname)}} \starttext \startbuffer[mathbuffer] \currentfontname $a^2 + b^2 = c^2$ $E = mc^2 \bigotimes \sum$ $α^2 + β^2 = γ^2$ \blank[big] \stopbuffer \getbuffer[mathbuffer] \usetypescript[lucida][texnansi] \setupbodyfont[lucida] \getbuffer[mathbuffer] \usetypescript[cambria] \switchtotypeface[cambria] \getbuffer[mathbuffer] \usetypescript[palatino] \switchtotypeface[palatino] \getbuffer[mathbuffer] \stoptext Latin Modern and Palatino/px work very fine. Lucida lacks greek and some operators. I found no embedded LucidaNewMath fonts in the resulting pdf. Cambria has a very ugly spacing. btw. in the wiki is described a ConTeXt command \showmathcharacters. This seems not to work anymore. The related file math-run.tex is not input at the time of format generation. Greetings Lutz P.S. will the key [texnansi] (or [ec]) remain necessary to switch to LucidaBright?
