My webapp generates a CSV file with normal UTF-8 encoding which contains Cyrillic symbols. The file reads just fine in python and the results also display in the browser. However, when I open it in programs like Excel or Editor, the cyrillic symbols are replaced by plain "????".
I tried adding a cyrillic font and adding a cyrillic keyboard, but it didn't solve the issue. I am running Windows 7 in German. Does anybody have any tips?
UPDATE
The problem even happens on a Russian laptop which normally supports cyrillic. On some forums I read something about a windows encoding - could this be the issue?
