Once when I got my hand on openbsd I was really happy to have black and white terminal, I, somehow, orienting much more with b/w colors..
Anyway I know just one option to do it.
export TERM="linux-m"
and openbsd used something else like "vt8.." i don't remember.
Now I have freebsd on my dedicated server, I want to have black and white terminal again. On bash it works perfectly even in sh, i got normal unicode in Midnight commander for example... but when I entering ZSH with TERM="linux-m" in mc I have unicode problem , edges just a bunch of letters...
in /etc/login.conf i've got this locales:
unicode|Unicode Users Accounts:\
:charset=UTF-8:\
:lang=en_US.UTF-8:\
:lc_all=en_US.UTF-8:\
:tc=default:
here's screenshots
