[vtkusers] Displaying the degree symbol "\u00B0" in vtkCornerAnnotation

[Alok]

I cloned the git repo some time time back and built from source
The vtkTextActor/vtkTextWidget seem to be working fine with unicode but I
see some other problems which make them unusable for me.

Any recommendations on how to check the difference between
vtkCornerAnnotation and the vtkTextActor will be great. Seems like an easy
fix

Thanks
