When I try to import my K4 digital report, some entries fail - I've noticed that their symbols contains special characters (like # , „ or § ) or non-standard latin characters (like Ö ) Workaround I need to: Unzip the k4 digital report Open blanketter.sru file in Notepad (or any other text editor, like TextEdit on mac) Locate the problematic row (I can find it using UPPGRIFT number) Rename the symbol to something else (e.g. NULL1 , NULL2 , etc.) Save Zip back the files
