I have been using the default one (sdimage-bootpart.wks)?

I have created a “wic” directory in my custom layer and copied 
sdimage-bootpart.wks into it as sdimage-project.wks without making any 
changes but “wic list image” throws an error with the new .wks file:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb0 in position 37: 
invalid start byte
