I have tried everything that I could find on the internet.
$> gconftool-2 --type string --set /apps/gnome-terminal/profiles/Default/encoding "en_US.UTF-8"
$> cat /etc/environment
...
LC_ALL="en_US.UTF-8"
$> locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
...
LC_ALL=en_US.UTF-8
But whenever I open a new gnome-terminal, my powerline symbols still show up as question marks, and Terminal->Set Character Encoding is set to "Current Locale (ANSI3.4-1968)" which I then change to UTF-8 manually and then things are fine.
I have already rebooted the system multiple times!
