Saving docx as txt

Jun 10, 2014 at 10:01 AM
I'm using NetOffice (1.6.0) for converting docx files to text:
var document = wordApplication.Documents.Open(fileName);
document.SaveAs(newFileName, NetOffice.WordApi.Enums.WdSaveFormat.wdFormatUnicodeText);
However, with non-ascii characters (lower german quotes, french chars) it's never the same like saving as *.txt from word itself.
Umlauts usually work, but the resulting file always appears to be ANSI, regardless of the chosen WdSaveFormat.

Anything I might have missed?
