Hi.
The command \iint is defined in context (mkiv) but it doesn't produce
the desired sign. What I should do to make it appear? (in log file I see
that LMMath font desn't contain such symbol but I don't know much about
font mechanism of context, btw in latex I could easily get that symbol
so I think it should be in 'standard' math font).
No, the symbol is not in the 'standard' math fonts, and this is trouble.
Like LaTeX, we also fake the glyph in MkII. In MkIV, we check if the font
contains that glyph; if not we fake it. Currently, that test is failing.
A temporary workaround (for LM) is to redefine:
\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}
and then \iint \iiint etc will work.
Hans, do you know what the \textfont check is not working for LM?
The ideal solution is to add esint glyphs to the LM math virtual font. I
did not work on this because I was assuming that opentype LM math will be
out soon. But it seems that right now, the only decent opentype math font
is Cambria. Both Stix and Asansa give really horrible spacing at times.
