I'm not sure what you mean by vtk2DActor, but it is possible to render
unicode text by configuring the vtkTextProperty's FontFamily to
VTK_FONT_FILE and setting FontFile to a font file that supports the
character you wish to use. The default fonts in VTK do not support
much if any unicode, so you'll need to provide a font file.

This approach will work for vtkTextActor, vtkTextActor3D, and vtkTextMapper.

Example: https://github.com/Kitware/VTK/blob/master/Rendering/FreeType/Testing/Cxx/TestFreeTypeTextMapperNoMath.cxx#L148-L159
