-//! Windows specific console TTY implementation
-//!
-//! This module contains the implementation of a Windows specific console TTY.
-//! Also converts between UTF-16 and UTF-8. Windows has very poor support for
-//! UTF-8 and some functions will fail. In particular ReadFile and ReadConsole
-//! will fail when the codepage is set to UTF-8 and a Unicode character is
-//! entered.
-//!
-//! FIXME
-//! This implementation does not account for codepoints that are split across
-//! multiple reads and writes. Also, this implementation does not expose a way
-//! to read/write UTF-16 directly. When/if Rust receives a Reader/Writer
-//! wrapper that performs encoding/decoding, this implementation should switch
-//! to working in raw UTF-16, with such a wrapper around it.
