Bug report #14411

When copying a shapefile with right-click "save as" it turns integer-type to string-type

I tried to copy shapefiles with several integer- and real-type columns with the right-click-menu "save as..." and it turned out, that the resulting new shapefile gets all interger-types formatted into string-types. As far as I tried, this only happens to former integer-types. Real-types are correctly copied to real.

The layer attributes of the origin shapefile say, that the integers have the type "qlonglong" and the typename "Integer64". Those are formatted into type "QString" with typename "String" when copying the shapefile.
