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

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
