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

My log says :
Missing character: There is no ⟺ (U+27FA) in font LMMath12-Regular!

Yes, in a unicode font Rightleftarrow (which is part of the definition of
\iff) is at 27FA. But LM fonts do not have any glyph which looks like
that....
So, as a temporary workaround, we redefine \Rightleftarrow in
math-pln.mkiv. But for some reason, that definition is not kicking in, and
ConTeXt still things that \Rightleftarrow is \Umathchar "3 "0 "27FA.
Hans, any idea why this is happening. char-def.lua is loaded before
math-pln.mkiv. Even then, why doesn't the redefinition in math-pln take
precedence?

well, math-pln is loaded beforemath-ini and that one does the
definitions so you need to revert that order in context.mkiv
probably ok now that math-pln is stripped to the bone but of course
*you* will test it -)

This works with the current alpha (most likely Hans fixed it).
