Same problem here, with Ubuntu 12.04 and TB 38.2.0. The received message is really UTF8, and it's headers (and multipart heders) seem correct (the sender used Apple Mail 2.2).
If I open the message in the viewer, it displays correctly, but under View->Character Encoding, TB has selected "Western" instead of "Unicode". When forwarding the message, it gets double-encoded. If in the viewer I change View->Character Encoding to "Unicode", the message still displays correctly, as if I didn't change anything, but now forwarding also works correctly and the encoding is preserved. It feels as if TB would ignore the mail headers and try to autodetect the encoding, getting it wrong. This auto-detected charset is then only used with forwarding, not for displaying the mail in the viewer, or for replies. Very strange. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1166104 Title: Forwarding a message breaks character encoding Status in thunderbird package in Ubuntu: Confirmed Bug description: I received an email (MIME, multipart, UTF-8 text specified for both HTML and Plain parts). When I click Forward Message then the encoding gets broken. It appears that the UTF-8 has been interpreted as Latin-1 (or at least not UTF8) and 'converted' into UTF8, even though it already was, so I see (what could be) double-encoded characters. The mail was from Yahoo: X-Mailer: YahooMailWebService/0.8.140.532 The message displays fine. If I hit Reply, that's fine. If I start a new message and copy-and-paste, that works properly. It appears to be just the Forward button that's broken. Both Forward and Shift-Forward exibit the same behaviour.
