README 文档

README

Unicode and Base64 routines at billions of characters per second in PHP using the simdutf library.

Accelerates Unicode routines (UTF8, UTF16, UTF32) and Base64 using SSE2, AVX2, NEON, AVX-512, RISC-V Vector Extension, LoongArch64, etc.

The simdutf library is already part of Node.js, Bun, WebKit, Chromium, Cloudflare Workers, and more. Now it can be used with PHP.
