+On Windows, if the file descriptor is connected to the console (e.g. `fd == 1`
+or `stdout`) a string encoded as UTF-8 or Unicode (`ucs2`) will not be rendered
+properly by default.
+It is possible to configure the console to render UTF-8 properly by changing the
+active codepage with the `chcp 65001` command. See the [chcp][] docs for more
+details.
