Steps to reproduce:
- Navigate to C:\ and open freeldr.ini (will be opened with ROS notepad)
- Set DefaultOS value to ReactOS_Debug (or any other possible value)
- Hit Ctrl+S or choose "Save" in the main menu
- Normally reboot the system via Start menu
Expected result: System is bootable, and default freeldr menu item is changed.
Observed result: System is not bootable anymore.
Actual reason: Notepad adds UTF-8 BOM at the beginning of freeldr.ini, though the file was never encoded with UTF-8 text encoding. This didn't happen some time before, so it's a regression.
