we can't find out how to set the character encoding of the a message
'subject' field to any charset different from iso-8859 or utf-8.

We want to send programmatically send messages with CDO where message
'Subject' field is in cyrillic (as in Outlook Express we can set the
encoding
of an outgoing message to any available charset - there should be some way
to set it programatically).

For example, when sending an email with charset set to koi8-r in Outlook
Express, we have following lines in message source:

Subject: =?koi8-r?B?wszBLcLMwS3CzME=?=

How to make this with CDO?

Thanks.
