mysql欧洲国家的文字乱码？英语、中文没有乱码是什么原因呢？0
【举例】波兰语Śląskie中的Ś和ą字母显示的是?
1.修改配置文件my.ini里的：
default-character-set = utf8
character-set-server = utf8
2.命令行设置：
mysql> show variables like 'character%';
+--------------------------+----------------------------------------------------
-----+
| Variable_name | Value
|
+--------------------------+----------------------------------------------------
-----+
| character_set_client | utf8
|
| character_set_connection | utf8
|
| character_set_database | utf8
|
| character_set_filesystem | binary
|
| character_set_results | utf8
|
| character_set_server | utf8
|
| character_set_system | utf8
|
| character_sets_dir | C:\Program Files\MySQL\MySQL Server 5.5\share\chars
ets\ |
+--------------------------+----------------------------------------------------
-----+
8 rows in set (0.05 sec)
mysql> show variables like 'collation%';
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database | utf8_general_ci |
| collation_server | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.00 sec)
mysql>
3.针对我创建的数据库，设置字符集为utf8：
alter database 数据库名字 character set utf8;
4.数据库表的字符集也是utf8
mysql> show create table customer_info;

5.在.jsp文件里：
contentType也设置了字符集为utf8；
pageEncoding也设置为utf8
基本上能设置的都设置了，还有什么需要设置的么？

附：
1.mysql版本是5.5

采纳的答案
还有很多地方涉及编码：
比如Java或者JSP代码文件本身的编码。
AP服务器设定的GET或者POST传输的编码。
JDBC驱动连接时候指定的编码。
如果内容是从外部文件读进来的，外部文件的编码也有影响。
。。。
如果能debug的话，可以看看在Java程序那边保存数据库之前在内存里面是否乱码了。
如果没有，基本可以肯定是JDBC驱动连接的写法或者数据库编码的问题。
如果已经乱了，可以从前台刚刚post到后台的时候debug看看数据是否乱码（或者是从文件里面读出来的时候），应该就是这时候乱了。这就是提交的数据没有正确编码。
如果数据不是提交的，是写死在程序里面的固定字符串，那么乱了的话就是程序文件本身编码不是UTF8。
不能debug的话就比较麻烦了，不过可以通过在上述地方加log来检测。
代码根本不让动就没招了。2014年11月05日 12:56
