Google's [[ https://en.wikipedia.org/wiki/Noto_fonts | Noto fonts ]] are freely licensed (SIL Open Font License), are "designed to cover all the scripts encoded in the Unicode standard", are "designed with the goal of achieving visual harmony (e.g., compatible heights and stroke thicknesses) across multiple languages/scripts", they don't look like crap, and most importantly, they support emojis ;)
These fonts are basically a huge gift with a bow on top to solve our multi-lingual SVG rendering needs. Can we install them on the scaling servers? Right now the [[https://noc.wikimedia.org/conf/fc-list|fonts the we have available]] are a random mishmash with incomplete glyph coverage and inconsistent quality and styling. (And many of them are just poorly-made ugly fonts made 10 years ago by free software enthusiasts.)
