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)

I get these symbols (Wrong spacing between ints, see below):

\usetypescript[asana]
\setupbodyfont[asana]

\starttext
\startlines
0x222B normal integral  $\int$
0x222C double integral  $\iint$
0x222D triple integral  $\iiint$
0x222E contour integral $\oint$
0x222F surface integral $\oiint$
0x2230 volume integral  $\oiiint$
\stoplines
\stoptext

Does it give the glyphs for you? If not, then something really is broken 
in your setup. Can you send me your log and output file offlist.

The spacing around \int is different in MkII and MkIV. One can get the 
right spacing by playing around with \dointkern

\def\dointkern
   {\mkern-6mu\mathchoice{\mkern-3mu}{}{}{}}

For asana, change -6mu to -16mu.

> I also need the space-time integral \iiiint (4 i's)

\definemathcommand[iiiint] {\repeatintegral{4}}

Is there a unicode slot for this?

Hans, we need a proper fallback mechanism for math glyphs. LM does not 
contain iint, etc, so we need to fake them, Asana and cambria do have 
them, so we should use the glyph from the font. Currently, the glyph is 
always faked.

\def\fakerepeatintegral#1%
   {\scratchtoks\emptytoks
    \dorecurse{#1}{\appendtoks \integralrepeatsymbol \dointkern \to 
\scratchtoks}%
    \appendtoks \intop \dointlimits \dodointlimits \to \scratchtoks
    \edef\dodorepeatintegral{\the\scratchtoks}}

\def\repeatintegral#1#2#3%
   {\let\dointlimits\donothing
    \let\dodointlimits\intlimits
    \iffontchar\textfont\zerocount#1\relax
     %\edef\dodorepeatintegral{\utfchar{#1}}%
      \let\dodorepeatintegral#2%
    \else
      \fakerepeatintegral{#3}%
    \fi
    \futurelet\next\dorepeatintegral}

% This is a temporary solution, as we will make a virtual glyph in lm.

\definemathcommand [iint]   {\repeatintegral{"222B}\normaliint  \plusone  }
\definemathcommand [iiint]  {\repeatintegral{"222C}\normaliiint \plustwo  }
\definemathcommand [iiiint] {\repeatintegral{"222D}\normaliiiint\plusthree}
