php中邮件乱码

Question

没有做过日文的，给一个繁体的文件头你看一下，估计日文也差不多-----=_NextPart_000_00F6_01C5D0B1.62AA6490
Content-Type: text/plain;
charset="UTF-8"
Content-Transfer-Encoding: quoted-printable如果是这样的话应该不会出现乱码，你在outlook中查看一下源文件，看一下你的邮件头。

Answer 1

邮件头是这样的：
X-Mailer: php
Mime-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: BASE64
上方标题不会出错，问题是下放显示的小标题会出错。真苦闷。
