API reference

SimdUnicode exposes a small, focused public surface in the SimdUnicode namespace.

Core types

• SimdUnicode.UTF8 — UTF-8 validation. The main entry point is GetPointerToFirstInvalidByte, with architecture-specific kernels (...Avx512, ...Avx2, ...Sse, ...Arm64, ...Scalar).
• SimdUnicode.Ascii — fast ASCII detection and scanning, including GetIndexOfFirstNonAsciiByte and its per-architecture variants, plus IsAscii/SIMDIsAscii extension methods.
