I can't read korean(even other languages) mail contents as like attached images. It has been occoured from when I upgrade to version 38.0.1. Is there somewhat changed? If I trun to view mode to source of that email message, there shows like below at the header, --=_alternative 00182EAD49257E6C_= Content-Type: text/plain; charset="ISO-2022-KR" I think the errors comes from that encoding method 'ISO-2022-KR'. because other email that has no problem, shows like below, Content-Transfer-Encoding: base64 Content-type: text/plain; charset=UTF-8 How can I read emails that has problem?
