This is not supposed to happen.  Emacs should test at startup whether
the terminal can display these characters, and if not, replace them by
ASCII equivalents.  Please try to figure out why this doesn't work for
you (it does for me, although not on a Linux terminal).

Let's first understand why the automatic detection doesn't work.  IME,
devising a solution for a problem we don't understand is not a good
idea.

Thanks.
