If you use the ':utf8' IO layer then perl just slaps the SvUTF8-flag on whatever it receives.
You need the ':encoding(utf8)' flag for perl to be more careful in its decoding.
Demo:
$ perl -le 'print "\xA0"' |
perl -e 'binmode(STDIN, ":utf8"); use Devel::Peek; Dump(<STDIN>)'
SV = PV(0x801838) at 0x8039e0
REFCNT = 1
FLAGS = (TEMP,POK,pPOK,UTF8)
PV = 0x207f20 "\240\n"\0 [UTF8 "\x{280}\n"]
CUR = 2
LEN = 3
