When a document in Inkscape is saved as a PDF, it seems by default Inkscape only embeds subset fonts into the PDF.

However, I have multiple Inkscape documents, which I am exporting as individual PDFs, and then combining into a single PDF. This results in lots of "duplicate" subset fonts in the final combined PDF, making the file size larger.

Is there any way to make Inkscape embed full fonts when exporting to PDF? Then the fonts can be effeciently deduplicated and subsetted if multiple Inkscape-authored PDFs are combined.

I've looked through the Inkscape options (including command line options), and Google hasn't been much help either. Does anyone have any advice on this?
