printable_binary. A serializer/deserializer for working directly with binary data in a way that is still human-readable (ASCII printable stays, delimiter chars -> similar-looking UTF8, control chars -> semantically-relevant UTF8 glyphs), but NOT breaking your terminal/editor. C, Zig, LuaJIT, WASM & Node.js; working demo @ https://pmarreck.github.io/printable_binary/
