Yes. Basically putting \a in messages is a wrong approach since such a
character has neither a graphical representation nor it influences
appearence of other characters. Additionally it's unclear what has to be
done when characters around \a are redrawn. Could you detail at which
events beep should be produced and propose a patch to add appropriate hooks?
On the other hand doing a BIOS call with \a is a valid way to produce a beep
