The FastUtf8 package provides efficient UTF-8 handling for modern C++ with support for legacy C.
It includes a FastUtf8::Uniseries C++ class that lets you target UTF-8 for internationalization. UTF-8 is all you need for working with most Internet-based content, and targeting it can slash bloat associated with unnecessary encodings. Included methods for expressive queries against semistructured internationalized content get outstanding performance results relative to prior methods. A family of C-compatible functions does the heavy lifting for FastUtf8 and can be called directly by legacy C code.
