Question

你查一查那边数据库的字符集是什么字符集,而你用JSP写进去的时候又是用什么字符集,例如:
mysql> show variables like "%char%";
+--------------------------+----------------------------------------+
| Variable_name            | Value                                  |
+--------------------------+----------------------------------------+
| character_set_client     | gbk                                 |
| character_set_connection | gbk                                  |
| character_set_database   | gbk                                  |
| character_set_filesystem | binary                                 |
| character_set_results    | gbk                                  |
