I also got the same error.
I solved this problem by editing the following file.

AirSim\MavLinkCom\mavlink\mavlink_sha256.h

This file has the following garbled characters, which should be fixed.

I think this character does not support 932 (shift_jis). If you have other similar errors, you can fix them by correcting the unsupported character.
