Roman Kvasov created LOG4NET-405:
------------------------------------

             Summary: SmtpAppender encoding changes
                 Key: LOG4NET-405
                 URL: https://issues.apache.org/jira/browse/LOG4NET-405
             Project: Log4net
          Issue Type: Bug
          Components: Appenders
    Affects Versions: 1.2.12
         Environment: Windows 7, net 4
            Reporter: Roman Kvasov


After update to log4net 1.2.12 email encoding changed and my mail client
fail to render unicode symbols.
I think changes made for issue https://issues.apache.org/jira/browse/LOG4NET-354 brake encoding in SmtpAppender
log4net 1.2.10 use utf-8 encoding by default, below headers from email
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: base64
after update on log4net 1.2.12 email encoding koi8-r
Content-Type: text/plain; charset=koi8-r
Content-Transfer-Encoding: quoted-printable
I think change default encoding from utf-8 is pretty strange.

Proposed fix:
Do not use Encoding.Default, let SubjectEncoding and BodyEncoding by default be null, on email send set encoding only if field not null.
