Having trouble with opExtrude on skText

Hello,
I am trying to make 3D text via a Feature script, but having trouble with the "holes" being filled upon opExtrude.
How do I get ride of the extra material?
Thanks

Maybe:
You want to use qSketchRegion() as a query that you pas to opExtrude, not to opPlane - just to make sure.
qSketchRegion also has an innerloop filter which may work -
qSketchRegion (featureId is Id, filterInnerLoops is boolean) returns Query
A query for all fully enclosed, 2D regions created by a sketch with the specified feature id.
filterInnerLoopsbooleanOptional
Specifies whether to exclude sketch regions fully contained in other sketch regions. Default is false.
As a work around, I wrote a filter to remove the internal regions, which is below.
I would still like to see a simpler solution.
Thanks for the feedback so far.

It looks like filterInnerLoops used to default to "true" in older versions of std, which is likely why you don't remember needing to specify the flag before.
Thanks!
Unfortunately, filterInnerLoops does not properly handle the case where there is more than one level of nested loops.
As an example, make a sketchText containing Unicode character 0x0298 (LATIN LETTER BILABIAL CLICK): ʘ (Use the Tinos font). This character is topologically equivalent to an "O" character with a dot in the middle of the "O". Extrude the sketch with filterInnerLoops, and in the resulting solid, you will see that the middle dot is missing.
