MySQL连接字符集问题

Question

我在Mac上使用带有MySQL的velosurf，没有任何编码问题，但是当我切换到Linux机器时，我从velosurf获得的值编码不正确。

我发现它可能是默认连接字符集的问题。在Mac上我得到了：

mysql> show variables like "collation_%";
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | utf8_general_ci   |
| collation_database   | utf8_general_ci   |
| collation_server     | latin1_swedish_ci |
+----------------------+-------------------+
3 rows in set (0.00 sec)

mysql> show variables like "character_set_%";
+--------------------------+--------------------------------------------------------+
| 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     | latin1                                                 |
| character_set_system     | utf8                                                   |
| character_sets_dir       | /usr/local/mysql-5.5.11-osx10.6-x86_64/share/charsets/ |
+--------------------------+--------------------------------------------------------+
8 rows in set (0.00 sec)

在linux机器上，我有：

mysql> show variables like 'collation_%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | latin1_swedish_ci | 
| collation_database   | utf8_general_ci   | 
| collation_server     | latin1_swedish_ci | 
+----------------------+-------------------+
3 rows in set (0.00 sec)

mysql> show variables like 'character_set_%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | latin1                     | 
| character_set_connection | latin1                     | 
| character_set_database   | utf8                       | 
| character_set_filesystem | binary                     | 
| character_set_results    | latin1                     | 
| character_set_server     | latin1                     | 
| character_set_system     | utf8                       | 
| character_sets_dir       | /usr/share/mysql/charsets/ | 
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

创建数据库时设置数据库排序规则和字符集。我的问题是我无法更改客户端/连接/结果的默认字符集。

此外，启动连接时似乎没有任何方法可以使用velosurf设置charset。

有什么建议吗？

Answer 1

MySQL有一个命令行标志来设置字符集。你可以试试吗？ --default-字符集= UTF8

Answer 2

我发现MySQL在以root用户身份连接时将始终使用默认字符集。但它适用于有限的用户（我应该从一开始就做的事情）。

这个“功能”似乎是特定于Linux的。至少在OS X中不会发生。
