The default bitmap font used by xterm in base has the left/right
guillemet characters in it, so as soon as one defines LANG (before
spawning xterm) it just works.  (I know because I really like that
bitmap font and happen to use it also for Emacs.)

The tty however doesn't, so if one has a UTF-8 LANG and happens to
open tog in a tty it fails: it renderes the left guillemet as â¹ which
i think is due ISO-8859-1?  This is a problem also with tmux since it
doesn't correctly render the box drawing characters either.
