When I try to replace values in a field with Greek Characters they appear as it should be in attribute, but when I save the edits and re open the attribute I see question mark.
The same thing happens also in Qgis 2.8.1.
I use windows 7 x64 ultimate.
On an other machine which runs windows 8.1 and ArcGis 10.2.1 I see the replaced Greek letters and after reopen the attribute but when I export the attribute in .dbf I don't see anything.
How can I fix this problem?
