解决方案: http://stackoverflow.com/questions/26256421/sql-load-data-infile-utf8-issue
即:
load data local infile '/path/to/sqlfile' into table xxx character set utf8 fields terminated by ',' lines terminated by ' ';
into table xxx 后紧接着指定字符集 character set utf8;
/path/to/sqlfile 放在/etc/my.cnf 文件datadir定义的路径下, 传值传相对路径。
