SurveyJS PDF Generator supports standard 14 PDF fonts. However, these fonts do not include glyphs for certain special characters and lack support for languages that use non-Latin character sets. To properly render a PDF form in this case, PDF Generator needs a custom font. This demo shows how to use the Noto Sans Korean font to generate a PDF form with Korean characters.

Call the DocController.addFont(fontName, base64, fontStyle) method to add a custom font to PDF Generator. This method accepts the following parameters:

  • fontName: string
    A custom name that you will use to apply the custom font.
  • base64: string
    The custom font as a Base64-encoded string. To encode your font to Base64, obtain it as a TTF file and use any TTF-to-Base64 online converter.
  • fontStyle: "normal" | "bold" | "italic" | "bolditalic"
    The style of the custom font.

To apply a custom font to a PDF document, assign its name to the fontName property in the IDocOptions object.
