I encountered this error, when changing over to a Japanese language document. "fonts > defining > unable to define latinmodernmath-regular.otf as [simplefonts:1-8pt-mm-mb--1] --------------------------- fonts > math: unset for global bodyfont simplefonts:1 at 12pt I think this is a unicode math font. Can I fix this by downloading the proper font? If so please tell me where I can find it. partial current setting: -------------- \usemodule[simplefonts] \mainlanguage[ja] \language[ja] \setscript[nihongo] % unknown if need or not %\definefont [kanjikana] [name:ipaexmincho] % for just a few characters try this \setmainfont[ipaexm] %changing this to mincho didn't change still used ipaexm I read somewhere that "latinmodernmath-regular.otf" was deleted from the system from TeXLive for some reason. Is loading a unicode font gonig to solve this? Thanks
