Encoding error while importing csv in postgresql?

Question

PostgreSQL

Error when importing csv file into table

ERROR: invalid byte sequence for encoding "UTF8": 0xcc 0xe0
��������: COPY wmi_decodes, line 1

The query code is generated by postgresql itself:

"C:\\Program Files\\PostgreSQL\\12\\bin\\psql.exe" --command " "\\copy public.wmi_decodes (mark, wmi, additional_code, manufacturer, mark_owner, country_code, country, additional_info) FROM 'A:/carinfo.csv' DELIMITER ',' CSV ENCODING 'UTF8' QUOTE '\"' ESCAPE '''';""

The database is in UTF-8, the csv file is also in UTF-8, UTF-8 is specified during import.

What is the problem and how to fix it?
