I have this topic over here too:
Your file has something in common with my example, in that the text characters in the file are taking one byte per letter, and not two bytes. That suggests some sort of Unicode related issue. I didn’t get any suggestions yet, but I just thought about whether the file was written on Windows 7, and Unicode was different in those days.
I will test that idea.
Didn’t help, Windows 7 was able to write the text with two bytes per character.
