Loading utf-8 encoded text into MySQL table

荒凉一梦 提交于 2019-11-27 04:22:43
I have a large CSV file that I am going to load it into a MySQL table. However, these data are encoded into utf-8 format, because they include some non-english characters. I have already set the character set of the corresponding column in the table to utf-8. But when I load my file. the non-english characters turn into weird characters(when I do a select on my table rows). Do I need to encode my data before I load the into the table? if yes how Can I do this. I am using Python to load the data and using LOAD DATA LOCAL INFILE command. thanks as said in http://dev.mysql.com/doc/refman/5.1/en
