Error : Angband requires UTF-8 support

[Tobias]

When I get angband form github ( both angband/angband and v4 ) I get this message when I try to run the game.
./src/angband: Angband requires UTF-8 support

When I run the v3.3.2 from my package manager, I don't get this error.

Does anybody know what I might be doing wrong?

EDIT:
I had my locale set wrong. Fixed it myself.
