unwanted characters are introduced automatically in sent email
Hello Team,
I noticed that when sending reply emails via Thunderbird email application, Thunderbird is automatically adding characters in reply which are visible only after email is sent.
For example, I have seen below two characters being introduced on two separate occasion. It appears that these characters are replacement of what some spaces from original emails from sender.
1) �
2) ??
Attached is screenshot of the two emails from sent folder.
Please advise why this happens and how to fix it.
Thank you Parry
