Hello,
There are more ways to typset formulas in context. One is to use mathml,
but there is a module called newmat (\usemodule[newmat]) and this is the
way I use math in context. And there is it possible to use \text{}.
International characters should not be a problem then.

Hope that helps you!

Here a short example how to use math with this module(you can use inline
math with $some math$ ):

\startformula
q = \delta \frac{{\partial p}}{{\partial x}} = \delta (\phi )p_{vsat}
(\theta )\frac{{\partial \phi }}{{\partial x}} = \left[ {\frac{{\delta
_a }}{{\mu (\theta )}}p_{vsat} (\theta )} \right]\frac{{\partial \phi
}}{{\partial x}} = k\frac{{\partial \phi }}{{\partial x}}
\stopformula

\startlegend
\leg k \\ water vapor permeability \\ \\
\leg K \\ water vapor permance \\ \\
\leg S \\ surface \\ \\
\leg L \\ length \\ \\
\stoplegend

Aligning is also possible:

\startformula\eqalign{
t_{L,early} & = t_{L,late} = t_{L,ray} \cr
& = 6\ \mu m \cr
}\stopformula
