Hi Torsten,
It's not CR that is encoding in ansi it's the CSV or text program you are using to display the exported file that is showing you ansi characters as the default.
For example, open Notepad and click on file, Open... Note you have options now:
Most program default to ansi, but not all have the ability to select unicode...
CR typically supports UTF-8 and be sure to select a font that actually includes unicode characters, MS ARIAL Unicode is a good test.
