[NTG-context] accented capital in XML, how to smash it?

[massifr at fastwebnet.it]

Hello list,
I have problems with accented capitals like "È" adding some vertical space
to their lines.
Is there a way to \smash them automatically?
That's because I'm typesetting XML and not directly using ConTeXt.

I tried an automatic translation with

\usemodule[translate]
\translateinput[È][\smash{È}]
...
\enableinputtranslation

but it does not work.
