Hi Uwe,
In version 3.3 I tried to solve the issue described in post 18 by adding BOM character on Windows only since it didn't fix Cyrillic characters on Mac. In new version -- 3.4 -- I added it again as it was in 3.2. However in the cell A1 three weird characters appear now (on Mac). I don't know how to get rid of them.
Regards,
Kas
