This would be only suitable if it is a global option,
but if I add a few shapefiles, they could come from different sources
and have different encoding in the dbf files.
Thus this looks like at least a property per layer.

Thuban has a ~/.thubn/thubanstart.py file and the sessions files usually 
contain all the information necessary to reload a set of layers.

Yes, this would be the export possibilities from the table view dialog.

If it is not in the shapefile and cannot be reliably detected means the user
must change it and it needs to be saved in the session file so it comes up
again as the user wanted it to be. I think adding a display and button to the 
table view is a good approach.
