[Dovecot] CMU Sieve pluigin missing proper charset support

Hello,

After testing the Sieve plugin for the LDA, I have noticed that it does
not handle charset issues properly. IETF draft says:

4.3.  Subject and From Parameters

   The ":subject" parameter specifies a subject line to attach to any
   vacation response that is generated.  UTF-8 characters can be used in
   the string argument; implementations MUST convert the string to
   [RFC2047] encoded words if and only if non-ASCII characters are
   present.  Implementations MUST generate an appropriate default
   subject line as specified below if no :subject parameter is
   specified.

(see http://tools.ietf.org/html/draft-ietf-sieve-vacation-07)

The problem is that the dovecot plugin does not convert the string to
RFC2047 encoded words, it treats it literally and thus sends malformed
(from RFC's point of view) message - with improper Subject field
encoding.

Any chances of getting that fixed?

greetings,
