[vtkusers] Chinese or Russian Text

[Richard Frank]

Hi,



We are trying to add unicode to our vtk render windows and we haven't been able to get it to work.



I modified the DrawText.cxx example with the following





// Setup the text and add it to the renderer
  vtkSmartPointer<vtkTextActor> textActor =
    vtkSmartPointer<vtkTextActor>::New();
  std::string testString = u8"I have a red car.";
  textActor->SetInput (testString.c_str());
  textActor->SetPosition2 ( 10, 40 );
  textActor->GetTextProperty()->SetFontSize ( 24 );
  textActor->GetTextProperty()->SetColor ( 1.0, 0.0, 0.0 );
  renderer->AddActor2D ( textActor );
 

  // Setup the text and add it to the renderer
  vtkSmartPointer<vtkTextActor> textActor2 =
      vtkSmartPointer<vtkTextActor>::New();
  std::string testString2 = u8"我有一辆红色的汽车。";
  textActor2->SetInput(testString2.c_str());
  textActor2->SetPosition(10, 80);
  textActor2->GetTextProperty()->SetFontFamilyAsString("Microsoft YaHei");
  textActor2->GetTextProperty()->SetFontFile("D:\\Projects\\DrawText\\msyhl.ttc");

  textActor2->GetTextProperty()->SetFontSize(24);
  textActor2->GetTextProperty()->SetColor(0.0, 0.0, 1.0);
  renderer->AddActor2D(textActor2);
  // Render and interact
  renderWindow->Render();


but nothing draws for the chinese text. Is there anything else needed? Or is it a bug?



I can make my DrawText.cxx, Cmake and font file available.



Thanks
