Status: RESOLVED FIXED

(MailNews Core :: MIME, defect)

+++ This bug was initially created as a clone of Bug #1324443 +++
https://hg.mozilla.org/comm-central/rev/9c1291d2e1f7521c2558e8c76f37a6b724c9be32#l1.12

When I send an e-mail with me as the sender and charset wind-1252, the From gets encoded as:
From: =?UTF-8?Q?J=c3=b6rg_Knobloch?= <[e-mail]>

Yet I get a complaint on the intent to encode the From header with the charset of the message.

Since encodeMimePartIIStr_UTF8 just ignores the charset passed in, it makes no sense to call it with a charset it will just ignore:
https://dxr.mozilla.org/comm-central/rev/9cb95ca4c3f7cbd473e78addb8e3607af6af8386/mailnews/mime/src/mimeJSComponents.js#442

This message is unnecessary and will scare people.

Besides, according to RFC 6532 headers can have raw UTF-8 but nothing else (https://tools.ietf.org/html/rfc6532#section-3.2).

Patch coming.

This ugly warning should also go from the other branches.
