    First, the character set of your MySQL VARCHAR column should be UTF-8.

    ALTER TABLE t MODIFY latin1_varchar_col VARCHAR(M) CHARACTER SET utf8;

    Then, you should just be able to use Statement.setString() without worry:

    PreparedStatement updateSales = con.prepareStatement("UPDATE COFFEES SET SALES = ? WHERE COF_NAME LIKE ? ");
updateSales.setInt(1, 75); 
updateSales.setString(2, "Colombian"); 
updateSales.executeUpdate():

    Things to be careful of:

    • If you are reading text from a file, make sure you are reading the file in the right character set. See the constructor of InputStreamReader.
    • Be careful if you have columns in the database that are not in UTF-8 format!

    That’s all I can think of at the moment.
