That will not do, at least not portably and if you care for older
systems.  At minimum you must test utf8 and utf-8 here.  Better to
conditionalize on "command -v locale" first, it may be missing as
such (but forgot the details, i however do it like that).
Maybe something like "grep -i -q 'utf-\{0,1\}8$'" or so.
