U have a typst template file mostly containig functions and variable defs. Then i have a docutil -> typst rewriter that makes use of the functions of the the template. i18n is a non problem for me, because i have source files containig the correct text, but i have created ttf fonts containing may international glyphs using fontutils. As sphinx and typst support unicode it just works. the PDF are then postprocessed and all glyphs not used are striped out of the pdf, also some pdf streams are removed to shrink the pdf
