Status: RESOLVED DUPLICATE of bug 961983

(MailNews Core :: Composition, defect)

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:17.0) Gecko/20100101 Firefox/17.0 (Beta/Release)

Steps to reproduce:

Given a message with Content-Type: text/plain;charset="UTF-16" and empty body, compose and send a reply.


Actual results:

The reply headers have Content-Type: text/plain;charset=UTF-16;format=flowed, but the reply body is encoded in us-ascii.

A mailbox file containing the original message and the reply is attached; only Received: headers have been trimmed for brevity.


Expected results:

The reply content-type header and the reply body should be consistent: either the reply body should be UTF-16-encoded, or the reply header should specify charset="us-ascii".
