    9696RFC23 has left some users unhappy, particularly with how encoding management is done with shapefiles. There are quite a few tickets on that issue and in #4808 a patch is proposed so that OGR drivers report their source encoding ( OGRLayer::GetEncoding() ). RFC23 should be amended if this approach was accepted.

     98== Expose shapefiles of type Polygon as MultiPolygon (and LineString as MultiLineString) ? ==
     99
     100The OGR Shapefile driver expose a layer geometry type Polygon, even if the shapefile contains multipolygons. This causes issues when converting such shapefiles with ogr2ogr to formats that have strict geometry type checking (PostGIS, Spatialite, etc...). A possibility would be to expose a layer geometry type MultiPolygon, and automatically promote single part polygons as multipolygons.

     102The issue is discussed in #4939.
