I believe sufficiently recent versions of ghc (but I don't know which; this may require 9.2.1) have an RTS option to use a new I/O manager, which among other things implements the widechar API for console I/O.

I found an email from Tamar https://mail.haskell.org/pipermail/ghc-devs/2020-July/019053.html that says the new Windows I/O manager is available in 8.12+, and is enabled with +RTS --io-manager=native

Given that 8.12 doesn't exist I presume the meaning was "the version after 8.10" which is 9.0. Tom
