Loading utf-8 encoded text into MySQL table

as said in http://dev.mysql.com/doc/refman/5.1/en/load-data.html, you can specify the charset used by your CSV file with the "CHARACTER SET" optional parameter of LOAD DATA LOCAL INFILE

Do not need encode your characters in the file, but you need to make sure that your file is encoding at UTF-8 before load this file to database.

Try

LOAD DATA INFILE 'file'
IGNORE INTO TABLE table
CHARACTER SET UTF8
FIELDS TERMINATED BY ';'
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
