Steps to reproduce

Hello,

In a program called scrcpy that I develop, I listen to Ctrl+C on Windows using SetConsoleCtrlHandler(windows_ctrl_handler, TRUE);:

665ccb32f5/app/src/scrcpy.c (L148-L149)

It works correctly in the default (old) Windows console (typically started by cmd.exe), Ctrl+C is catched and the program can terminate gracefully (finishing writing a video footer for example).

However, from Windows Terminal, it has been reported that Ctrl+C terminates the process abruptly (which in that case cause the recorded mp4 file to be corrupted, but any other cleanup actions cannot be executed): https://github.com/Genymobile/scrcpy/issues/5122#issuecomment-2243087702

Is there a reason for this behavior?

Thank you for your help.

Expected Behavior

The Ctrl handler should be executed on Ctrl+C.

Actual Behavior

The process is killed abruptly on Ctrl+C.
