[vtkusers] Displaying the degree symbol "\u00B0" invtkCornerAnnotation

[John Platt]

Hi,

In VTK 5.10, I have only had success with vtkUnicodeString text arguments 
...

    std::ostringstream ostr;
    ostr << ang;
    vtkUnicodeString label(vtkUnicodeString::from_utf8( 
ostr.str().c_str() ));
    vtkUnicodeString deg( 1, 0xb0 );
    label += deg;

Not much help with vtkCornerAnnotation::SetText().

John.

I accidently hit post too quick earlier:


Here's the completed and corrected post:

Hey,

This is a silly question.
I have been trying for a while to display a degree symbol in 
vtkCornerAnnotation.

The way I am trying to do it is like this:
std;:string angle = computeAngle()+"\u00B0";
cornerAnnotation->SetText(3,angle.c_str()); //where cornerAnnotation if of 
type vtkCornerAnnotation.

This displays something like 50° rather than 50°
When I display the string on a terminal it works as expected.

Am I missing something here?

This displays something like 50A&circ&deg
