vtkCornerAnnotation and tabulation

Hi,

I create a vtkCornerAnnotation with some text including tabulation but the tabulation are not shown.

This an example how I use vtkCornerAnnoation:

std::stringstring ss;
ss << u8"My perfect text with some \t tabulation";
vtkNew<vtkCornerAnnotation> annotation;
annotation->SetText(0, ss.str().c_str());
....

Does anyone have the same behavior?

Thank you
