    Summary: Relies on undefined behavior of `char::from_u32_unchecked`

    Details: The Windows implementation of this crate relied on the behavior of `std::char::from_u32_unchecked` when its safety clause is violated. Even though this worked with Rust versions up to 1.42 (at least), that behavior could change with any new Rust version, possibly leading a security issue. The flaw was corrected in version 2.0.0.
