[NTG-context] m-letter.tex -- backslash interpretation error

[Rob Ermers]

Dear Friends,

It seems I am really having a problem. The backslash in my import 
document yields “.

\startsetups[letter:content]
\input brieftekst
\stopsetups

My document (brieftext.tex) among other things contains the following 
string:

ge\"interesseerde, which yields --> ge“”interesseerde

I am unable to use any normal code in my text, which is very problematic!

Kind regards,

Robert
