Hi Hans & Aditya Please be patient as I am not a developer just someone who writes documents. I discovered the integral symbols starting at the double integral are now composed by repeating the normal integral symbol n-times. However in an earlier email I commented that they didn't look right (something to do with setting the displaystyle (I think)) Then I discovered the Asana math font which has "correct" glyphs The missing symbols for math-vfu.lua are Asana math font 0x222B normal integral \int 0x222C double integral \iint 0x222D triple integral \iiint 0x222E contour integral \oint 0x222F surface integral \oiint 0x2230 volume integral \oiiint I also need the space-time integral \iiiint (4 i's) but could not find it in the Asana font Note for the other math stuff the Asana math font does not work like vectors and such. For $\vec{r}, \vec{R}$ the vector symbol is shifted to the right and not aligned above the character (hope this make some sense otherwise forget it for the moment). Kind regards gummybears
