Running the hello.com tutorial compiled in WSL2 in a CMD.exe prompt on Windows 10 corrupts it about cosmopolitan HOT 4 CLOSED

Thanks for the report. It seems what was happening is that the virtual processing terminal mode was persisting across processes. I've now fixed things so that exit() will restore the console mode.

After you run it, you can no longer use the arrow keys to go to the previous command, instead it prints the control characters: ^[[A

same issue on my machine. build on WSL2, run in WSL2 - OK, run in win32 CMD.exe - as above.

A temporary workaround for this is to run in a Powershell console, where this doesn't happen, or just run CHCP 437 after running the APE binary. It seems like it's not resetting the code page after changing it to 65001 (UTF-8) in https://github.com/jart/cosmopolitan/blob/master/libc/runtime/winmain.greg.c.

See also https://ss64.com/nt/chcp.html for more on CHCP.

Edit to add: actually, it seems you can just run CHCP with no arguments to stay in UTF-8 code page, but somehow this resets the console state so that arrow keys work again 🤷

It looks like we ought to grab the codepage at the beginning and then restore it on exit. I'll take a look at doing that and see if that is what is causing it. It worries me that it got fixed without resetting the codepage. Maybe there is something else that needs to be reset.
