Jmeter adds extra characters  when reading from a csv

Question

I'm reading some values from a csv like this:

But I'm getting some strange extra characters at the beginning of the ID value like this:

The CSV file is just an id, a name and line breaks. Why do I get these other characters?

Answer 1

The specific characters you see ( or EF BB BF in hex) are Byte order mark for UTF-8. So it is coming from your CSV file, likely somehow added on saving the file. So try to set File encoding parameter to UTF-8, it should help.
