Encoding changes suddenly, UTF-8, unreadable emails
Why I post this issue: I've read many threads about similar issues, but most are about issues occuring when replying, or seem older, or suggested solutions that didn't work for me.
Issue description: On Thunderbird 102.7.2, (64 bits) on Windows 11, I have this recurring problem: Some emails that I can read perfectly for quite some time, suddenly becomes "encoded" wrong (gibberish characters). It might happen after moving them into subfolders, but I'm not sure, since it only happen on a few rare emails (that happen to be important). Example : "d=C3=A9marrer la th=C3=A8se le 1er D=C3=A9cembre". This looks like UTF-8. It also adds random quotations where there should be none.
Attempts to resolve so far: - I have excuded C:\Users\me\AppData\Roaming\Thunderbird from Windows defender, as it was suggested somewhere an antivirus could be the issue, but the issue happened again. - The "Charset menu" addon was suggested, but UTF-8 is already selected, and I cannot select another charset. - "Repair encoding" produces no effect. - Moving back the email to another folder also has no effect.

Hello, some precisions. To clarify, the problem is deeper than just character encoding of the email, as it seems its content has been overwritten by another email earlier in the conversation. Concretely we have: - email 1 from A to B - reply from B to A - reply 2 from A to B First two emails are as they should look. Last email has a wrong encoding AND its content seems to be that from the earlier email 1, not its original content; the actual content of the reply is moved to the bottom of the email, after this string of characters:
