any appreciated!

thanks vtk developers.
vtk supports non ascii text.
have specify font file on vtktextproperty -- default fonts in vtk support ascii.

the following example use droid font display chinese characters.

vtksmartpointer<vtktextactor> textactor =         vtksmartpointer<vtktextactor>::new(); textactor->gettextproperty()->setfontfamily(vtk_font_file); textactor->gettextproperty()->setfontfile("/usr/share/fonts/truetype/droid/droidsansfallbackfull.ttf"); textactor->setinput("utf-8 freetype 中文: \xe4\xb8\xad\xe6\x96\x87");
