Using UTF-8 in FreeBSD
First we need to set the LC_ALL and LANG variables, find out which locales can support UTF-8.
cd /usr/share/locale/; ls *UTF-8 -d
Add the following environment variables to the appropriate file, ~/.profile or ~/.login or ~/.bashrc.
export LANG=sv_SE.UTF-8 export LC_ALL=sv_SE.UTF-8
Now login and logout to have the effects apply.
