there’s a proprietary word processor that’s prevalent where I live called Hangul (*.hwp). their public HWP format documentation is terrible and until very recently there weren’t many methods to read HWP files other than using their proprietary windows/mac program. then very recently some dev ‘vibecoded’ a web based equivalent in rust/wasm here and it works surprisingly well. occasionally a few documents are distorted but otherwise it’s great for viewing.
