489760 - Messages copied to IMAP sent items have accents (é,à,ù...) replaced by question mark (?)

Status: VERIFIED DUPLICATE of bug 488282

(Thunderbird :: General, defect)

Description

[Merome]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.9.0.9) Gecko/2009040821 Firefox/3.0.9
Build Identifier: version 2.0.0.21 (20090302)

Thunderbird is configured to copy all sent messages to the standard sent items of an Exchange 2007 IMAP folder.
The sent messages are copied in the right place, but some of them (near all of them) have the accentuated letters in the body replaced by a question mark. Note that accents in the mail subject are OK.

When choosing a non-Exchange IMAP folder for copying sent items (local folder or other imap server), the problem disapears : accents are well copied.
When copying manually a mail in the Sent Items Exchange IMAP folder, there is no more problem : accents are well copied too.

In all cases, received messages are correctly encoded, only the copied message have no more accent.

Reproducible: Sometimes

Steps to Reproduce:
1. Write a new message with accentuated letters in it.
2. Send message
3. Check the sent message body in Sent Items folder
Actual Results:  
In the sent message body, accentuated letters are replaces by "?".

For example, the following message :
Subject : chère maman
Body : à bientôt

Is diplayed in the sent folder like that :
Subject : chère maman
Body : ? bient?t




Expected Results:  
The body of the message copied in the sent items folder should have all accents.

Some users have reported this problem on IMAP Gmail too (in french : https://www.geckozone.org/forum/viewtopic.php?p=413369).

If Thunderbird is able to copy "manually" a message with accents, it should be able to copy the sent item correctly.

Note that sometimes, accents are well copied with exactly same configuration. I can't figure out why and when.

Better having a duplicate than missing a bug :-(.
