Research direction

Start at WKTWriter.toString and trace how empty Point and ShapeCollection values are serialized. Reproduce the reported outputs, then verify that empty geometries serialize as POINT EMPTY and GEOMETRYCOLLECTION EMPTY without changing non-empty WKT output.

Written by the indexing model from the issue text.

Description

bug enhancement

When putting an empty Point through WKTWriter.toString, it produces a string of the form POINT () or POINT(NaN, NaN) instead of POINT EMPTY. Similarly for an empty ShapeCollection, we get the serialization GEOMETRYCOLLECTION () instead of GEOMETRYCOLLECTION EMPTY.
