Python：MySQLdb庫編碼問題

Question

我有一個MySQL數據庫。我將charset設置爲utf8;

... 
    PRIMARY KEY (`username`) 
) ENGINE=MyISAM DEFAULT CHARSET=utf8 | 
... 

我使用MySQLdb在python中連接到db;

conn = MySQLdb.connect(host = "localhost", 
           passwd = "12345", 
           db = "db", 
           charset = 'utf8', 
           use_unicode=True) 

當我執行查詢時，響應正在使用「windows-1254」進行解碼。響應示例;

curr = conn.cursor(MySQLdb.cursors.DictCursor) 
select_query = 'SELECT * FROM users' 
curr.execute(select_query) 

for ret in curr.fetchall(): 
    username = ret["username"] 
    print "repr-username; ", repr(username) 
    print "username; "username.encode("utf-8") 
... 

輸出是;

repr-username; u'\xc5\u0178\xc3\xbckr\xc3\xbc\xc3\xa7a\xc4\u0178l\xc3\xbcli' 
username; şükrüçağlüli 

當我用「windows-1254」打印用戶名時，它工作正常;

... 
print "repr-username; ", repr(username) 
print "username; ", username.encode("windows-1254") 
... 

輸出是;

repl-username; u'\xc5\u0178\xc3\xbckr\xc3\xbc\xc3\xa7a\xc4\u0178l\xc3\xbcli' 
username; şükrüçağlüli 

當我用西裏爾字母這樣的其他字符嘗試它時，解碼會發生變化。我怎樣才能防止它？

我覺得INSERT到數據庫時編碼錯誤的項目。

我推薦的python-ftfy（從https://github.com/LuminosoInsight/python-ftfy）（幫了我一個呈三角問題）：

import ftfy 

username = u'\xc5\u0178\xc3\xbckr\xc3\xbc\xc3\xa7a\xc4\u0178l\xc3\xbcli' 
print ftfy.fix_text(username) # outputs şükrüçağlüli
