When using emacs from terminal with -nw option (with or without -Q),
some characters are not working properly. It's somehow keyboard layout
half messed up. Characters like ö,ç,ü are working but ş (U+015F), Ş (U+15E),
ğ (U+011E) and Ğ (U+011F) are not working. ş is return _ and Ş is return ^. i is working but instead of İ, 0 is returned. Changing the coding system cp1254
(Windows Turkish) doesn't have any effect. It's discovered by
