hello Tadziu, > What viewer are you using?
i tried both with zatura and evince > Does the PDF render okay if you use gv to display it? i didn't know gv can render pdf files and it happens it's the only one to render math.pdf the file correctly. pdffonts math.pdf name type encoding emb sub uni object ID ------------- ------- --------- --- --- --- --------- Symbol Type 1 Custom no no no 5 0 Times-Italic Type 1 Custom no no yes 8 0 shows that Symbol is not emb. i thought fonts were always embeded in pdf files... yet: i'm not sure about what to be fixed. thanks and regards marc
