This seems be able to be explained and perhaps not a bug.
According to POD of encoding.pm,
(see http://search.cpan.org/~dankogai/Encode-2.40/encoding.pm )
"\xDF" under use encoding "iso 8859-7" is \x{3af} in Unicode
"\xA4\xA1" under use encoding "euc-jp" is \x{3041} in Unicode
Then, under use encoding "utf8", U+00A0 in Unicode should be "\xC2\xA0".
Use of "\xA0" expecting U+00A0 is wrong.
The reason why /[\x7F-\x80]/ matches U+00A0 is that /[\x7F-\x{FFFD}]/
matches U+00A0 as \x80 is malform as utf8 and replaced with \x{FFFD}.
