Changing Data source encoding through layer Properties worked well for me until version 3.0.x - now, the field is grayed out and shows only UTF-8. Our Data sources are quite mixed and I get spades, question marks etc. instead of East European characters when labelling. Is this feature broken in Early Adopter release or am I missing something?
Checking or unchecking value in Settings/Options/Data Sources/Data source handling - "Ignore shapefile encoding declaration" returns error "Wrong value for parameter "GRASS7 folder - Specified path does not exist".
