[vtkusers] Does vtkCaptionActor2D support chinese characters?

[Liu_tj]

Hi, Dave,

I am using Activiz .NET. In C#, the string is UTF16 and I convert it to UTF8. And I follow your step. It doesn't work. If I convert to UTF8, the characters are not displayed. If I don't convert, the characters are displayed as ??.

As you said, we need unicode font file. How can I identify the font file is unicode font file.

Thanks

vtkCaptionActor2D will work.


You'll need to provide a unicode font file (the embedded fonts in VTK only support ASCII) via the caption actor's GetCaptionTextProperty:


captionActor->GetCaptionTextProperty()->SetFontFamily(VTK_FONT_FILE);
captionActor->GetCaptionTextProperty()->SetFontFile("/path/to/some/unicode/font/file");


and then encode the caption text as UTF-8.


Hope this helps,
Dave
