Are you saying that you see the same problem as the OP?  Because the
problem you described earlier was different.

If you start "emacs -Q -nw" in a cmd.exe window, then type ş, what
happens?  And what does "C-h l" report after that?

Also, what happens if you type "C-x 8 RET 15f RET", do you see the ş
character on display, or do you see something else?

There are now keyboard layout files on Windows.  Does it help to
evaluate this:

  M-: (w32-set-console-codepage 857) RET

If that doesn't help, try this instead:

  M-: (w32-set-console-codepage 1254) RET
