xxUTF – SIMD Unicode Normalization

xxUTF is a high-performance library that accelerates Unicode normalization (NFC, NFD, NFKC, NFKD) using SIMD instructions, targeting developers of text-processing tools, databases, and compilers. It is interesting because it achieves up to 10x speedups over standard ICU implementations, making it critical for applications that need to process large volumes of international text efficiently.
