byteSize != sizeof (char)? Error?

Unity Engine
1

Hi,
I wonder what the error “byteSize != sizeof (char)” means.
It is written to my console all the time (this is not caused by a compiling error).

At the bottom of the console I can read : “Assert in file: PropertyEditorController.mm at line: 611”.

Thanks /Aron
