I am using context minimals, with the simpleslides module to
make a presentation.
I noticed that when typesetting math formulas, I get missing characters.
I finally tracked it down to an issue (stupidity from me?) with the
"context" executable.
I made a new file, with some example math markup, posted below
----------
\starttext
And this is some maths with PostScript fonts.
\startformula
{a \over b} = {c \over d} \iff ad - bc = 0,
\qquad \int_0^{2\pi}\!\!\! \sin^2(x)dx =\pi,
\qquad {\rm e}^{{\rm i}\pi} + 1 = 0,
\qquad \sum_{k=1}^{\infty}{1 \over k^2} = {\pi^2 \over 6}.
\stopformula
Some ligatures: ffi, ffl.
\stoptext
-----------
When running "context test_math.tex", in the output file I don't see the
"\iff" symbol. When running "texexec test_math.tex", everything is working fine.
Any help would be appreciated, and sorry if this is a stupid question.
Thank you,
Andrei Dragomir
