That would sort of work but be a suboptimal fix, it imposes a run-time test
on everyone just to save the file in a legacy encoding when saving the file
as
utf-8 (or as ascii with accents shown as commands) has no run time cost and
places the file in the default text encoding used by almost all current
systems.
