As in "C:\cygwin64\Cygwin.bat" that can be found after a regular install of
Cygwin

Uh, no? Mine looks like this. Again this is the file installed by Cygwin, not
something I have home brewed:

   @echo off
   C:
   chdir C:\cygwin64\bin
   bash --login -i

I am not doing this, I am just using Windows explorer to go to "C:\cygwin64",
then double clicking "Cygwin.bat"

I dont want mintty. As you know mintty adds another "layer" to the situation,
another process. If I was using mintty I would not have discovered this problem
in the first place. Some might say good, but no. It is important that even
launching Cygwin via Cygwin.bat/bash.exe works in a sane manner; and that it not
sacrifice features that even cmd.exe has, which is the current situation.

Prior to "Cygwin.bat", it says 65001, because I feel that is the proper default
for Windows. I set it like this:

   REG ADD 'HKCU\Console' /v CodePage /t REG_DWORD /d 65001 /f

Yes, However I do not think this is germain to the conversation, as I have found
you can change it "live" without issue.

Cmon man, give me a break here, I am trying. I have been posting on this issue
for months, and Id rather not keep regurgitation the same stuff over and over.
At any rate, here is the text from that link,
LATIN SMALL LETTER O WITH DIAERESIS' (U+00F6):

   $ chcp.com 65001
   Active code page: 65001

- Alt 148 outputs nothing
- Alt 0246 outputs nothing
- Pasting this character does not work

   $ chcp.com 437
   Active code page: 437

- Alt 148 works
- Alt 0246 works
- Pasting works

and here is why 65001 is needed at all:

   $ cat omega.c
   #include <stdio.h>
   int main() {
    printf("Ω\n");
   }

   $ x86_64-pc-cygwin-gcc -o cygwin.exe omega.c
   $ x86_64-w64-mingw32-gcc -o mingw32.exe omega.c
   $ chcp.com 65001
   Active code page: 65001

   $ ./cygwin.exe
   Ω

   $ ./mingw32.exe
   Ω

   $ chcp.com 437
   Active code page: 437

   $ ./cygwin.exe
   Ω

   $ ./mingw32.exe
   Ω
