> UTF-8, for example, allows to encode the character "ä" as \xc3\xa4 OR \x61\xcc\x88. They look visually identical, yet fail any string comparison. Well-designed high-level programming language (see Perl6) compares strings depending on how they look, not on their binary representation [0]. For example let's play with Perl6 REPL: > my $a = Blob.new(0xc3, 0xa4) Blob:0x<c3 a4> > my $b = Blob.new(0x61, 0xcc, 0x88) Blob:0x<61 cc 88> > $a eqv $b False > $a.decode() eqv $b.decode() True > $a.decode() eq $b.decode() True As another example, Python3 would fail: >>> a = b'\xc3\xa4' >>> b = b'\x61\xcc\x88' >>> a == b False >>> a.decode() == b.decode() False Perl6 is definitely going to dominate the world one day.
