關於big5轉utf8的問題 - Linux

是這樣的。

因為各種網路建言
想把上古時代完全沒有宣告編碼的Mysql+big5 server全部改成utf8編碼
但是在dump&reload的時候碰壁
目前是已經成功用各種偏方
可以看到dump出來的.sql裡面有顯示正確中文

(那個把.sql先用latin1 reload回Mysql
再重新用latin1 dump出來讓Mysql當翻譯官的神奇辦法)

但是把這份.sql iconv成utf8並且把內文latin1 sed 成 utf8之後
再reload回character_set已經重新設定成utf8的Mysql時出現了亂碼

檢查local之後總覺得好像不太對勁
想貼上來請大大幫忙判斷一下是哪邊出了什麼問題

以下為舊系統配置
CentOS release 5.5 (Final)

在新系統配置下目前.sql文件是可以看到正確顯示的中文
但那個
LC_CTYPE=en_US.ISO8859-1
我怎麼看都覺得怪怪

有沒有大神知道我要怎麼改.sql文件編碼和系統編碼
才可以再reload到新系統Mysql的時候可以正確顯示中文

拜託各位大神了
謝謝各位大神m(_ _)m
