Dos下连接mysql后，运行一下几项就可以插入中文了：

SET character_set_client = gbk;
SET character_set_connection = gbk;
SET character_set_database = gbk;
SET character_set_results = gbk;
SET character_set_server = gbk;

SET collation_connection = gbk_bin;
SET collation_database = gbk_bin;
SET collation_server = gbk_bin;
