Please explain why i get a incorrect string value error

[Doug Barger]

I have a csv text file that has chars 32-127 only, Filtered out all other chars.
i am getting this error during import;

Error Code: 1366. Incorrect string value: '\xEF\xBF\xBDs b...' for column 'pcdbpartsdescriptionPartsDescription' at row 6168

here is the code generating the error;

load data infile 'C:\\ProgramData\\MySQL\\MySQL Server 8.0\\Uploads\\Pass0.csv'
into table autoscratch.pass0
fields terminated by ','
enclosed by '"'
lines terminated by '\r\n'
ignore 1 rows;

I don't understand why this is a problem, it is a simple text file. I have read allot about code-pages, i have read all the posts i can and i cannot find an answer that makes sense.
