Hi

The following math symbols are missing,

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)

Kind regards

PS Using latest stable context (MK-IV)
