Hello,
As the title states when using savePdfAsString to generate a PDF, the HTML questions containing French charachters (é, è, ç, à, …) are not showing properly.
Please see this plunkr to generate a pdf using the "save as string" button, and the attached pictures below.
PS: Using {htmlRenderAs: "image"} makes any html content containing these characters disappear all together from the generated PDF.
