Just wondering. Some CSV files have it, some don’t. Should that be removed? Does it batter if it is there? I use MacOS, is this related to Windows?
It may be a BOM (byte order mark) used to give a hint that the file has Unicode text encoding:
Generally Easy Data Transform will handle BOMs without you knowing about it.
If you don’t want to output a BOM then uncheck Byte Order Mark when you are writing to a file.
Does that help?
