Export Orders csv character support

Hi again,

go to Manage Orders / Export Orders and press Download. I either save or view the csv file. When viewing, excel opens up. Anything non-latin (greek in my case) is not displayed well. When saving, I get a csv file. If opened with notepad characters are OK, if opened with excel non-latin are not OK. Before asking, I confirm that any other sheets or csv's with non-latin characters opened in my computer through excel works well!

Is it an ANSI, UTF-8 thing? can you help on that?
