I'm still having this problem, but I am stuck on Thunderbird 17.04 on Ubuntu Linux. Even though there are newer versions available for Windows. I previously had set the Default Character Encoding to UTF-8 the Character Encoding had been set to Western (IS0-8859-1). If this is being reset by an upgrade, it is possible that other things are being changed that affect this issue.
