actionmailer编码 - 在电子邮件客户端中呈现垃圾 [英] actionmailer encoding - rendering garbage in email client

问题描述

我有电子邮件的文本和HTML部分。在电子邮件包含来自数据库的值的情况下，用户报告垃圾字符。当涉及unicode字符时，这似乎是一个问题。我创建了一个简单的模板，只是回显了文本和html部分的值（<％= @body_text％> ）并用一个示例字符串测试：

，然后是文本部分：

Content-Type：text / plain; charset = UTF-8 Content-Transfer-Encoding：
base64

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: base64

和html部分：

Content-Type：text / html; charset = UTF-8 Content-Transfer-Encoding：
quoted-printable

Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable
