请教关于squirrelmail简体繁体乱码问题

yangjiaozhu1

两个用户假如都是简体中文环境或者都是繁体中文环境,相互发邮件正常,但一方简体环境,另一方繁体环境时,收发的邮件都是乱码,需要改成相应的环境才能正常显示,有什么办法让系统自动转换吗?

思一克

自己将自己的语言设置正确.

不要在英文设置下发其他语言的邮件. 也不要这样转发

台湾和大陆的公司共用一个邮件系统,没办法啊

caodh

你们用的什么邮件系统哦
没采用UTF-8的编码呀

我自己寫了一個patch，加入了charset detection功能，會依照郵件內的Content-Type或subject選擇合適的編碼，回覆和看附件時都會用同樣的encoding.....前提php要打開output_buffering.....如小弟的劣作有任何何bugs煩請告知，謝謝

将.po文件都转换为utf-8编码，并将配置文件全改为utf-8格式就不会出现乱码了。
具体涉及到如下文件：
conf/config.ini.php的default_charset
function/i18n.php的lang[zh_CN][]和lang[zh_TW][]
