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 -) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

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.

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

Sorry, was testing using an old version .... Aditya
