pdfFont property
Settings for a custom font for the exported PDF, when using the
offline-exporting
module. This is used for languages containing
non-ASCII characters, like Chinese, Russian, Japanese etc.
As described in the jsPDF docs, the 14 standard fonts in PDF are limited to the ASCII-codepage. Therefore, in order to support other text in the exported PDF, one or more TTF font files have to be passed on to the exporting module.
See more in the docs.
