User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4 Build Identifier: Thunderbird 2.0.0 It is not possible to send all mail in UTF-8 (like gmail can do). In preferences, one can configure UTF-8 as default encoding for outgoing mails, there's also an option to use this default character encoding on replies. However, when a message is inline *forwarded*, it's by default forwarded in its original charset, unless the user changes encoding to UTF-8 manually for each message. The best solution would be to rework the option "Use the default character encoding in replies" into "Use the default character encoding in replies and forwarded messages" so one can send *all* outgoing mail in UTF-8. Better yet, there could be a single option "Send all mail in UTF-8". Reproducible: Always Steps to Reproduce: 1. 2. 3.

Looked at mailnews/compose/src/nsMsgCompose.cpp The code snippet providing the default charset for replies is quite strightforward: // use send_default_charset if reply_in_default_charset is on. nsCOMPtr<nsIPrefBranch> prefs (do_GetService(NS_PREFSERVICE_CONTRACTID)); if (prefs) { PRBool replyInDefault = PR_FALSE; prefs->GetBoolPref("mailnews.reply_in_default_charset", &replyInDefault); if (replyInDefault) { nsXPIDLString str; NS_GetLocalizedUnicharPreferenceWithDefault(prefs, "mailnews.send_defa ult_charset", EmptyString(), str); if (!str.IsEmpty()) LossyCopyUTF16toASCII(str, charset); } } Would it be possible to put identical code into function which handles inline-forwarding? Thanks, Petr

Requeued into Message Compose and changed Severity to normal. Most other mail clients do the same for replies and forwards, so current behaviour of Thunderbird is non-standard and confusing.
