#change The engine now accepts a -UTF8Output command line argument which allows the output stream to be in the correct mode.
#change UAT accepts the same UTF8Output parameter to allow the connecting streams to be in the correct mode too (though it's currently only passed during the UnrealPak invocation).
#add FPlatformMisc::SetUTF8Output added to allow the opting-in of a UTF-8 output stream in Windows.
