[Dovecot] How can i set vacation subject in non-english characters?

[Zhang Huangbin]

Hi, all.

I have implemented vacation via dovecot sieve. but how can i use
non-english characters in vacation subject?

Thanks very much.

This is my sample sieve rule for vacation:

----8<----
require ["vacation"];

vacation
    :days 1
    :mime
    :subject "Auto-Reply: Out of office."
"MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

I can use non-english character here as mail body, wrote in utf-8.
";
----8<----

-- 
Best Regards.
