Hi,
I second Even argument and I would prefer to change QGIS implementation.
It does not make sense to have QGIS WKT strings not compatible with
other Python tools (based on GEOS/JTS, like shapely, for example) and ogr.
>>> import shapely
>>> shapely.to_wkt(shapely.Point(0, 0, 0))
'POINT Z (0 0 0)'
>>> shapely.from_wkt('POINT Z (0 0 0)')
<POINT Z (0 0 0)>
Regards,
Jorge Gustavo

Hi,
Both formats are compliant with the WKT specifications.
Are they? I may have missed something in the Simple Features spec, but
looking at https://portal.ogc.org/files/?artifact_id=25355 , I can't
see where it would allow the form {geometryTypeName}Z without a space
between {geometryTypeName} and Z.
For example the BNF at page 56 shows:
<point z tagged text> ::= point z <point z text>
The examples at page 62 also show a space.

A minimal example is below. Executing it will return an exception:
"RuntimeError: OGR Error: Corrupt data"
from osgeo import ogr
qgis_geometyry = QgsGeometry().fromWkt("POINT Z (0 0 0)")
wkt = qgis_geometyry.asWkt() # 'PointZ (0 0 0)'
ogr.CreateGeometryFromWkt(wkt)
