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}.
