commit https://github.com/vim/vim/commit/ac360bf2ca293735fc7c6654dc2b3066f4c62488 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Sep 1 20:31:20 2015 +0200 patch 7.4.852 Problem: On MS-Windows console Vim uses ANSI APIs for keyboard input and console output, it cannot input/output Unicode characters. Solution: Use Unicode APIs for console I/O. (Ken Takata, Yasuhiro Matsumoto)
