Could you build this?

No Accelerating Unicode normalization using SIMD vector instructions requires microarchitectural optimization and expert understanding of the Unicode standard's complex canonical decomposition and composition rules.

What it would actually take: The system must be implemented in Rust, C, or C++ using architecture-specific SIMD intrinsics (AVX2, AVX-512, ARM NEON) or hand-tuned assembly. It requires mapping the entire Unicode Character Database canonical classes into vector registers, efficiently handling branchless combining-character sorting, and managing variable-length UTF-8 multi-byte decoding in SIMD lanes. This demands rare domain expertise at the intersection of CPU microarchitecture, vectorization, and low-level text encoding standards.
