It's faster than iostream and typed, unlike scanf. Think of {fmt} or std::format in C++20, but in another direction.

simdutf
Unicode routines (UTF8, UTF16, UTF32) and Base64: billions of characters per second using SSE2, AVX2, NEON, AVX-512, RISC-V Vector Extension, LoongArch64, POWER. Part of Node.js, WebKit/Safari, Ladybird, Chromium, Cloudflare Workers and Bun.
Lemire and collaborators often write in C++ intrinsics, or thin platform-specific wrappers on top of them.
I count ~8 different implementations [1], which demonstrates considerable commitment :) Personally, I prefer to write once with portable intrinsics.
