hello Tadziu,

i tried both with zatura and evince

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
