<p>I've went ahead and added support for PointZ like WKT strings in
OGR in <a class="moz-txt-link-freetext" href="https://github.com/OSGeo/gdal/pull/10370">https://github.com/OSGeo/gdal/pull/10370</a>, but it would be
probably better that QGIS writes conformant WKT by default (I
suspect that fixing this has the potential of breaking a number of
tests though)<br>

<p>Are they? I may have missed something in the Simple Features
spec, but looking at <a class="moz-txt-link-freetext"
href="https://portal.ogc.org/files/?artifact_id=25355"
moz-do-not-send="true">https://portal.ogc.org/files/?artifact_id=25355</a>
, I can't see where it would allow the form {geometryTypeName}Z
without a space between {geometryTypeName} and Z. <br>
</p>
<p>For example the BNF at page 56 shows:</p>
<p><point z tagged text> ::= point z <point z text></p>
<p>The examples at page 62 also show a space.<br>
</p>
<p>Even<br>

A minimal example is below. Executing it will return an
exception: <br>
"RuntimeError: OGR Error: Corrupt data"<br>
<br>
from osgeo import ogr<br>
<br>
qgis_geometyry = QgsGeometry().fromWkt("POINT Z (0 0

wkt = qgis_geometyry.asWkt() # 'PointZ (0 0 0)'<br>
