LLVM 21 has stricter warnings for character type conversions: - URLPatternParser: Change isValidNameCodepoint to accept char32_t since codePoints().begin() returns char32_t, not char16_t - EncodeURIComponent: Add explicit static_cast for char16_t to char32_t - highway_strings: Use FixedTag<uint8_t, 16> instead of ScalableTag for the preloaded vector array, since SVE types are sizeless and can't be stored in C++ arrays. Use ResizeBitCast to convert back to scalable vectors when comparing. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
