The `smtp-send-message` and `standard-header` functions do not attempt any encoding --- which means that it ends up encoding in UTF-8, while the receiving end probably interprets it as Latin-1.
There's a `net/unihead` library that provides an `encode-for-header` function that's suitable for encoding a subject line: > (encode-for-header "中文标题" ) "=?UTF-8?B?5Lit5paH5qCH6aKY?=" Oddly, the `net/unihead` library appears to be undocumented; I'll fix that. Instead of encoding the content, you might be able to just add Content-Type: text/plain; charset=UTF-8 to the header of your message. If I remember correctly, that should work as long as the receiver is happy with 8-bit mail content (which seems to be the case from the information that you've provided).
