MySQL連接字符集問題

Question

我在Mac上使用帶有MySQL的velosurf，沒有任何編碼問題，但是當切換到Linux機器時，我從velosurf得到的值編碼不正確。

我發現它可能是默認連接字符集的問題。在Mac我：

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) 

雖然Linux機器上，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) 

數據庫整理和字符集，當我創建數據庫進行設置。我的問題是我無法更改客戶端/連接/結果的默認字符集。

此外，似乎沒有任何方法可以在連接啓動時用velosurf設置字符集。

有什麼建議嗎？

Answer 1

我發現MySQL以root身份連接時總是使用默認字符集。但是對於有限的用戶來說它確實可行（我從一開始就應該這樣做）。

此「功能」似乎是Linux特定的。至少在OS X中不會發生這種情況。

Answer 2

MySQL有一個命令行標誌來設置字符集。你可以試試嗎？ --default-character-set = utf8
