with mail.connect() as conn:
for user in selectemail:
    message1 = request.form['htmltext']
    sender='garni.kh@gmail.com'
    subject = "hello, %s " %user[1]
    msg = Message(recipients=[user[0]],
                  html=message1,
                  subject=subject,
                  sender=sender
                  )

    conn.send(msg)

当我在我的 html 中使用时，这段代码运行良好

普通英文字体

但是当我使用波斯语字体时它不起作用。

     <h1>فونت فارسی</h1>

我有这个错误表单烧瓶：

     builtins.UnicodeEncodeError
     UnicodeEncodeError: 'ascii' codec can't encode character '\u0633' in position 659:     ordinal not in range(128)

这是烧瓶中的完整错误：

潜在的问题是，当您将str(unicode在 Python 2 上) 传递给字符串时，smtplib.sendmail该字符串被编码bytes为 ASCII。当您只传入 ASCII 字符时，一切正常，但是一旦传入一组非 ASCII 字符（如فونت فارسی），就会出现编码错误。

解决方法是自己将消息编码为字节，提供正确的编码：

msg = Message(recipients=[user[0]],
              html=message1.encode("utf-8"),
              subject=subject,
              sender=sender
              )

这message1.encode("utf-8")会将 unicode转换为以 UTF-8 编码表示这些字符str的流。bytes当smtplib.sendmail检查消息的内容时，它会发现它已经是一个字节流，并且不会尝试再次对其进行编码（从而解决您的问题）。
