Is it possible to export national characters to PDF?
One node has name “Bętąóśżćń” . National characters disappeared after export

That’s very odd.
The first step that the sample does is render it as SVG.
But if you look at the SVG, all of the text is faithfully rendered.
So it appears to be a bug in the svg-to-pdfkit package.

What did you do?

I imported font Calibri to document and I changed the default font from Helvetica to Calibri in the svg-to-pdfkit. Calibri supports national characters
