Hi, I'm sorry but couldn't really reproduce this bug in my dev environment focusing it on an econding problem.
Instead i found a way to properly render the diacritics in the email headers and gonna submit a patch in relation with bug 744077. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=744077 The patch could fix this problem but as long as i cannot reproduce it i can't be sure about it. So i prefer to send the patch to the other ticket also because it is directly related to its title. If you have any ideas about how to reproduce it, they're more than welcome. Bests, efkin.
