PDFKit works fine for me, but when I render symbols like ₹ and č, it doesn't show up at all (not even as character garbage).
I'm not converting a web page, I'm manually creating a PDF. Do I have to set a charset? If so, how?
And I know the fonts have the characters — I'm using the same font on the web with no problems (Open Sans).
Edit: The PDFKit live demo can't seem to handle these characters either.
