If you'd still like to try to get the arrow characters to work, here is my answer from Why does my nerd tree have these odd characters. I run Arch Linux, so your mileage may vary.

I had this exact same problem and was able to fix it by uncommenting UTF-8 and leaving ISO-8879-1 commented out in /etc/locale.gen. Then I ran locale-gen and restarted. Also added 'export LANG=en_US.UTF-8' to my .bashrc. Here are the results of my locale settings once it started working:

[lysistrata@(none) ~]$ locale -a
C
en_US.utf8
POSIX
[lysistrata@(none) ~]$
