The solution with the way things are currently, is just to use modelines (within the first 3 lines of the file) which are supported in your favorite editor, vi or emacs:
% -*- coding: utf-8; Mode: erlang; tab-width: 4; c-basic-offset: 4; indent-tabs-mode: nil -*-
% ex: set softtabstop=4 tabstop=4 shiftwidth=4 expandtab fileencoding=utf-8:

You just need to make sure modeline support is turned on (vim seems to default modeline support to off).
