     12 * This mapper supports two-way mapping, but it is optimized for the case of Windows to BCP-47.
     13 * It also supports normalizing and canonicalizing the Windows strings.
     14 *
     15 * See the [Rust documentation for `WindowsParser`](https://docs.rs/icu/latest/icu/time/zone/windows/struct.WindowsParser.html) for more information.
