More precisely, it destroys its argument when Encode::FB_CROAK is
provided as the third argument to encode().

###
$ perl -MEncode -wle '$a="abcd"; encode("utf8", $a); print "a=<$a>\n"'
a=<abcd>

$ perl -MEncode -wle '$a="abcd"; encode("utf8", $a, Encode::FB_DEFAULT);
print "a=<$a>\n"'
a=<abcd>

$ perl -MEncode -wle '$a="abcd"; encode("utf8", $a, Encode::FB_CROAK);
print "a=<$a>\n"'
a=<>
