Hello,

thera were some problems concerning accented characters in math (mathml) a while ago (as far as I remember they were solved). But some tiny bugs apparently remained there.

Minimal example: $\cases{&\ccaron}$

is there a problem in the ec vector? compare:

Not exactly a problem. The texnansi ones work thanks to the (semi-)coincidence that the accent-part of the font encoding is identical to Knuthian encoding, and that simply doesn't work for less knuthian encodings like ec, where this is not the case.

Perhaps you have to introduce a macro like \buildmathaccent ...

actually, \cases{&\tf \ccaron}$ works ok

Without the \tf, \characterencoding is '@default@' instead of '@ec@'. Does that help pinpoint the problem?

this seems to work, the problem is that there is no \everyfam

\starttext

\def\enableencodinginmath {\appendtoks \everyhbox{\mr\everyhbox\emptytoks}% \everyvbox{\mr\everyvbox\emptytoks}% \to \everymath}

\enableencodinginmath

$\cases{& \ccaron}$

$x=\hbox{\ccaron$x=\hbox{\ccaron}$}$

\stoptext
