Need help exporting form data. Encoding problem?

First I tried form auto. The listing looks fine in the back end but when export to CSV, all the asian characters are messed up. I checked the form's SQL table and it's using utf8_general_ci which should support my language. Please see attachment #1

The CVS file opens up correctly in Notepad however.... If I use notepad to save-as with UTF-8 Encoding, without doing anything else at all, this file will then open and show properly in Excel.

Any idea how to fix this problem? Any help appreciate, thanks!
