bug#42099: Emacs -nw Turkish Layout Problem

[Yigit Emre Sahinoglu <yigitemres@gmail.com>]

w32-get-console-codepage = 437 (#0665, #x1b5). Problem still exists as
I described (ö, ç, ü works but ş, İ (types 0), ğ are broken.)

"M-: (setq w32-use-fallback-wm-chars-method t)" does nothing. Problem
still exists (I check the value if it's correctly set with
describe-value).
