+A wide string Rust library for converting to and from wide strings, such as
+those often used in Windows API or other FFI libaries. Both `u16` and `u32` string types are
+provided, including support for UTF-16 and UTF-32, malformed encoding, C-style strings, etc.
+
+Macros for converting string literals to UTF-16 and UTF-32 strings at compile time are also 
+included.
+
+*Requires Rust 1.58 or greater.* If you need support for older versions of Rust, use 0.x versions of
+this crate.
