Description

Redmine - does not follow the RFC2047, as the line should not be longer than 75 character.

The following example shows how a large line should be:
Content-Type: text/plain; name=
"=?iso-2022-jp?B?GyRCJCIkJCQmJCgkKiQrJC0kLyQxJDMkNSQ3JDkkOyQ9JD8bKEI=?=
=?iso-2022-jp?B?GyRCJEEkRCRGJEgkSiRLJEwkTSROJE8kUiRVJFgkWyReJF8bKEI=?=
=?iso-2022-jp?B?GyRCJGAkYSRiJGQkZiRoJGkkaiRrJGwkbSRvJHIkcyMxIzIbKEI=?=
=?iso-2022-jp?B?GyRCIzMjNCM1IzYjNyM4IzkjMBsoQi50eHQ=?="

The following RFC describe how the message header should be for Non-ASCII Text
