Should have been included as default with Thunderbird, but for some reason it is not. I converted recently from Eudora and was forced to fix errors in email messages because Eudora could not handle utf-8 properly. HeaderToolsLite addon came in handy, however that addon removes the 'replied to' arrow. ToggleReplied can easily add it again.
