Setting the main font to ipaexm for Japanese characters, causes the sample document below to fail being typest properly. The $\diamond$ symbol I specified as an item bullet does not get typeset and where is should be is blank. Though not shown in this example, the default set is also affected. When it should be a circular bullet a largish hypen - is displayed. Also parsing of the document text itself is affected with Context halting in the middle of the first item's text. I think all problems are due to the change in fort. Is there anyway I can specify a backup font or a fort to use for only the symbols, which I believe is in a math font? Any assistance it getting this working will be much appreciated. Thank you. ---- # 1 Sample Context Macro document that causes the errors: ---- \usemodule[simplefonts] \setmainfont[ipaexm] \definesymbol[5][$\diamond$] \starttext \startitemize[5,columns,unpacked,two,broad] \item 此の行にbulletを打つ。 \item One more column for good measure \stopitemize \stoptext --- end of sample Context macro doc. ---- #2 sample of the errors output by Context ---- system > cont-new.mkiv loaded ... system > beware: some patches loaded from cont-new.mkiv . . fonts > latin modern fonts are not preloaded languages > language en is active loading > ConTeXt User Module / Simplefonts fonts > typescripts > unknown: library 'loc' {/usr/local/texlive/2012/texmf-....../context/mkiv-base.map} fonts > defining > forced type otf of latinmodernmath-regular not found fonts > defining > font with asked name 'latinmodernmath-regular' is not found using lookup 'file' fonts > defining > unknown font latinmodernmath-regular, loading aborted fonts > defining > unable to define latinmodernmath-regular.otf as [simplefonts:1-12pt-mm-mr--3] fonts > defining > forced type otf of latinmodernmath-regular not found fonts > defining > font with asked name 'latinmodernmath-regular' is not found using lookup 'file' fonts > defining > unknown font latinmodernmath-regular, loading aborted fonts > defining > unable to define latinmodernmath-regular.otf as [simplefonts:1-12pt-mm-mr--2] . . fonts > math: unset for global bodyfont simplefonts:1 at 12pt fonts > math: unset for global bodyfont simplefonts:1 at 12pt !
