Embed a Font when exporting to PDF

When I use the export function in the preview and export to PDF, I can’t see an option to also embed all fonts.
Or is there an automatic algorithm that will control it like described here:

Hi Martin,

yes, that is correct.

Since version 26 the export option PDF.FontMode does not exist anymore, because in the new PDF exporter this specification is no longer necessary due to the automatic always using the option optimized for the display and file size (CID, embedding, subsetting etc.).
