Simdutf Can Now Be Used Without libc++ or libc++abi

This article details how the simdutf library, a low-level C++ library for UTF-8 validation and conversion, has been updated to remove its dependency on libc++ and libc++abi. The author explains the benefits of this change, including better portability to embedded systems, WebAssembly, and freestanding environments, simplified cross-compilation, reduced binary size, and easier static linking. The article discusses the technical approach taken, such as introducing a stl_compat.h header that provides minimal implementations of C++ standard library types when libc++ is not available. This update is significant for developers working on projects like Ghostty that previously depended on simdutf and needed to eliminate C++ runtime dependencies.
