Inkscape supports converting text to a variety of stroke fonts: Extensions → Text → Hershey Text.

The fonts are SVG, stored in /usr/share/inkscape/extensions/svg_fonts/ under Linux.

I recently took EMS Readability from there and adopted it into a code base that is generating reMarkable documents with strokes and all (rather than PDFs) in support of reverse-engineering actually good rendering, as I wanted text in my generated documents.
