Sometimes the fieldnames in the QGIS attribute table get corrupted, mostly it is å, ä, ö that is changed when the layer is opened in another software.
Is there any way to change them or is it only solution to create a new field and copy data to new field?
Yes shapefile, when I am opening the shapefile in ArcView3.2 I cant choose encoding and its get corrupted. There are somethings that is so much easier in ArcView so I am still using it.
